Ok, so, there are a few apps that don't work well under x86_64. Mplayer (because of the 32-bit codecs), Firefox, java, and a few others. Obviously I can download and compile from source, but is there a safe way to install 32-bit rpms via yum without borking the rest of my system? Mplayer-i386, for example, has a bunch of i386 lib dependencies which are obviously not installed, so even compiling from source would end up being a pain.
