Oops. You're right, sorry. Misread your numbers. 6 fps is broken, of course.

Question Re: Linux kernel 2.6.28-git2 breaks Nvidia driver, problem with PATs and MTRRs

It seems that NVidia has no intention to correct this already old bug. It's a shame.
I've no idea how to configure the kernel in order to "turn off 'x86 PAT support' ".
