In the alternate ending, Matt is *not* shown at college (as he is in the original version) but instead he is wearing a suit and smoking a cigar - standing at Capitol Hill, where we assume he is now working.
There is an workprint version of the film floating around on the Internet including some of the deleted scenes from the DVD and alternate shots; also including a couple of minor deleted scenes not seen on any other version.
The unrated DVD version contains more nudity and sex which was originally trimmed or altered to avoid an "NC-17" rating.
