While I don't know about scholarships - I can tell you that the University of Illinois Champaign-Urbana (a top 10 school) does provide a number of disability services in a well established program.
My husband utilized DRES regularly throughout his undergrad years - and continues to while pursuing his graduate degree. (http://www.disability.uiuc.edu/) He has found them to be especially helpful and supportive.
Upon looking over the page, I see that they do have a link for DRES scholarships!
