I'll throw my vote for Worcester Polytechnic Institute (http://www.wpi.edu) as a school that has a diverse undergrad CS program.

It also has a wealth of other engineering students (chemical, electrical, mechanical, and industrial) who are forced to co-mingle to avoid going outside in the awful Worcester winter.

Despite not being as well-known as some of the more famous engineering schools, in the years since going, I've run into a lot of really sharp folks who also went.

I'd at least recommend it as one to look into.
