Hi, Here at Plumíferos, we also have some AMD 64 workstations. At first, 
we used them with Ubuntu 64, but run blender under a 32 bit environment, 
through dchroot. Now we moved all the workstations to 32 bit linux 
because it wasn't confortable to work with both architectures. My 
advice: If you can, go to pure 32 bits, if not, try a chroot environment.

Regards.
