i'm running FC5 x86_64 on an AMD Athlon64 3400+ box and haven't had a 
single problem regarding the 64-bit processor or the 64-bit OS ... 
before, i was running FC4 32-bit on an Intel Pentium 4 1.6GHz and this 
new system blows it away with just as few problems as I had on the 
original 32-bit hardware.  i haven't had any major show-stopper problems 
w/ 0.20 on FC5 x86_64 and the only problems i've had were cosmetic 
issues w/ mythweb
