I think that is a bit excessive. I would much rather say that the Nvidia 9755 driver hags with a 2.6.20.x kernel while running on GA-K8NSC Mobo, but even then, two sample is not enough to draw such a conclusion.
What is the brand and model of your graphics card? It seems much more likely to me that a given graphics card model would cause the problem. Why does my card work with the previous drivers (I used something like 87xx)? Why am I getting frame rates that are 10x faster on UT2004 while running a demo in 32bits instead of 64bits? There are too many variables and unidentified symptoms! Unfortunately, I don't know where to start probing. The hard lock with the 9755 drivers and the 18.104.22.168 kernel was a complete show stopper so I came here to seek the word of the wise.
My graphic card is a PNY Verto GeForce 6800GT 256MB.
