Subject: PAT support (or lack of) for Pentium 3 CPU's

It has come to my attention that PAT support has been disabled for P3 CPU's in kernel versions 2.6.30 and later due to a bug in the CPU. 

I have attempted to get the NVIDIA proprietary drivers working with these kernel versions and 3 different Pentium 3 motherboards, all have failed. The drivers seem to require PAT support in order to work correctly, each board has in fact produced a different error when using only MTRR.

Can a kernel option be added to enable/disable PAT for P3 CPU's? Or is there any possible workaround for the bug?

I'd be interested to hear from Radeon users running a 2.6.30 or later kernel.

For anyone wondering why I still use such an old machine, I require ISA support.

Cheers,

Brad Allen
