What’s a “racial disparity”? By what yardstick does one measure when a racial disparity in college admissions exists?
I'm not at statistician, but I assure you that given that many of the factors involved can be quantified, than various forums of analysis can be done on recorded data. I'm sure you are familiar with statistics, correct?
"Princeton University researchers have found that ignoring race in elite college admissions would result in sharp declines in the numbers of African Americans and Hispanics accepted with little gain for white students.
In a study published in the June issue of Social Science Quarterly, authors
Thomas Espenshade and Chang Chung examined the controversial notion that eliminating affirmative action would lead to the admission of more white students to college and found it to be false. The assertion that qualified white students are being displaced by less qualified minority students was a prime plaintiff argument in the 2003 U.S. Supreme Court cases against the University of Michigan (Gratz v. Bollinger and Grutter v. Bollinger).
"We're trying to put these admission preferences in context so people understand that lots of students, including those with SAT scores above 1500, are getting a boost," said Espenshade, the professor of sociology who co-authored "The Opportunity Cost of Admission Preferences at Elite Universities" with Chung, a senior technical staff member in the Office of Population Research. "The most important conclusion is the negative impact on African American and Hispanic students if affirmative action practices were eliminated."
According to the study, without affirmative action the acceptance rate for African-American candidates likely would fall nearly two-thirds, from 33.7 percent to 12.2 percent, while the acceptance rate for Hispanic applicants likely would be cut in half, from 26.8 percent to 12.9 percent. While these declines are dramatic, the authors note that the long-term impact could be worse.
"If admitting such small numbers of qualified African-American and Hispanic students reduced applications and the yield from minority candidates in subsequent years, the effect of eliminating affirmative action at elite universities on the racial and ethnic composition of enrolled students would be magnified beyond the results presented here," the report says.
The authors also cite other studies and the actual experience of the University of California system where affirmative action has been eliminated: "The impacts are striking. Compared to the fall of 1996, the number of underrepresented minority students admitted to the University of California-Berkeley Boalt Hall Law School for the fall of 1997 dropped 66 percent from 162 to 55.... African-American applicants were particularly affected as their admission numbers declined by 81 percent from 75 to 14, but acceptances of Hispanics also fell by 50 percent. None of the 14 admitted African-American students chose to enroll. Of the 55 minority students admitted, only seven enrolled in the fall of 1997, a falloff that had the effect of reducing the underrepresented minority share in the first year class to 5 percent in 1997 compared with 26 percent in 1994."
Removing consideration of race would have little effect on white students, the report concludes, as their acceptance rate would rise by merely 0.5 percentage points. Espenshade noted that when one group loses ground, another has to gain -- in this case it would be Asian applicants. Asian students would fill nearly four out of every five places in the admitted class not taken by African-American and Hispanic students, with an acceptance rate rising from nearly 18 percent to more than 23 percent. Typically, many more Asian students apply to elite schools than other underrepresented minorities. The study also found that although athletes and legacy applicants are predominantly white, their numbers are so small that their admissions do little to displace minority applicants.
The authors based their work on models previously developed in a 2004 study where they looked at more than 124,000 elite university applicants' SAT scores, race, sex, citizenship, athletic ability and legacy in combination with their admission decision. This more recent study honed in on more than 45,000 applicants.

It may the case that there are other methods more effective at addressing such discrepancies, since they are likely more to do with economic, housing, and early education segregation, then say, the subtle racist tendencies of people who poor over college admissions.
If the problem is just ignored instead and not redressed at all, because it's unconstitutional (you know, the document that legally enforced slavery for almost a century) as you stipulate, which has yet to be determined since the Justices have yet to rule on it, I suspect Americas racial problems will backslide and getting severely worse, as if they weren't already.
As mentioned in the OP, the Court has explicitly said that racial quotas and/or “racial balancing” are unconstitutional. The reason is because such methods of racial discrimination do not meet the strict scrutiny standard of narrow tailoring.
Affirmative action =/= racial quotas.
Every university is limited in the number of students it can accommodate next year.
I guess if every university was able to accept every applicant, everyone would go to Harvard or Yale or Columbia or Stanford.
Again, you seem to be working on the incredibly mistaken notion that any of those schools maintain some empirically sound means of determining what student is more likely to do better than any other given student, that students are admitted to schools based solely on how smart they are (why exactly do schools maintain so many sports teams again?), and that the students admitted do so because they crossed a threshold of admittance, when in fact, they are selecting a part of the population that is already qualified to attend a school, but are not perceived to be the best 500 out of the 4000.
