Question about x64 and running x86 programs

[Kris Moore]

Figured I'd give you guys an update on this also. I got all the 
libraries loaded, and everything into place, but it seems the suppot is 
only "so-so" at best. About every other binary crashes, or segfaults 
with varying errors. I have quite a few QT programs, and they are all 
compiled on the same machine, with the same libs and such, but its 
really hit-n-miss on which ones work. Anybody know if the 32bit binary / 
shared library support is really still this shaky?
