If startups hire CS majors, they code. CS at your college probably isn't pure theory, but rather closer to Software Engineering. And you can't expect college to teach you everything that you'll need to know on your own. Take this summer and spend it hacking on a project you find interesting. Learn a particular language (preferably one that your college wont go over. Be it Haskell, Ruby, a Lisp variant, whatever) and learn it as well as you can in a few months. Then when the next summer rolls around, you'll have two years of class + that summer building something on your resume. And that summer will help out a lot in terms of practical experience working on a project (as opposed to a 1-2 week assignment that you drop as soon as it's handed in for a grade).
