I guess there are several ports that will not work 64-bit, we just  
haven't come across them yet. I imagine a lot of the bugs currently  
classified as Snow Leopard-related issues are in fact 64-bit-related.  
So far I see the following ports forcing themselves to 32-bit builds:

bochs
synergy
wine
wine-crossover-games
wine-devel
