everything ive tried so far behaves fine, except for pd, and i think that shouldnt be much longer..

the lower end of amd64 line is fast and cheap, same as always for amd..you wll get a significant performance improvement in 64bit mode due to the extra general purpose registers, even before factoring in gains due to sse2 vectorization, etc.. 

worst i had to do was change a few longs to ints, and add -fPIC here and there..it shouldnt affect anything on your list however..
