Mario,
The opteron can run 32bit and 64 bit code so you may be running a 32bit
nvidia driver. The itanium is not enabled the same way, IIRC. There
really isn't 64bit GLSL support from Nvidia or ATI yet.

I disagree, the new HP SVA line (Opteron 64 bits) has GLSL support and
in fact I'm running VMD with GLSL rendering without trouble. Well, as
usual, it says my driver is buggy, but it works.
Ciao!
