You should consider schools which do not have direct admission to the CS major, but where declaring the CS major is open (i.e. required grades no higher than C, required GPA no higher than 2.0), or where the GPA threshold is low enough that you probably will want to do a different major if you get a lower GPA.
http://talk.collegeconfidential.com/discussion/comment/19262574/#Comment_19262574 is a list of secondary admission requirements (obviously does not include every possible school). You may want to add the schools where the CS major is open to declare (of course, there could be many others not listed here). Many of the others do have direct admission to the CS major, although many of these may also admit to the school but not the major if the applicant does not make the cut for direct admission to the CS major.
