I found FC1 to be completely unstable on my x86_64 machines, but before I upgraded I was able to run things like Matlab and Mathematica just by installing the proper libraries. Unfortunately there were indeed issues because occasionally the 32-bit and 64-bit versions of packages conflict. No such problems so far with FC2; I would definitely recommend it over FC1. - J<
