[64studio-users] disabling 3d acceleration

[Yoav Avitzour]

Yeah, I tried commenting out both dri and glx, still no go (with nv). As I 
said before, I would like to be able to use nv and _not_ nvidia. The main 
reason is that nvidia freezes my computer with the kernel from 1.4. For 
now I am able to work with the older kernel, but I thought that getting nv 
to work would not be a big problem and would allow me to use the testing 
branch fully. Turns out I was wrong, and perhaps nv cannot work with my 
card at all. Anyway, I'll just wait and try the newer kernels as they come 
along, and hopefully at some point they will stop freezing my system and 
I'll be able to upgrade. 

Thanks for the help,
Yoav
