On 18 Apr, Vasilios Hoffman spewed forth: :: look at the documentation that comes with the linux kernel :: (Documentation/mtrr I think), it tells you to echo a line to /proc/mtrr :: :: basically you find the start of the linear framebuffer for your graphics :: card (told to you when you run startx or xdm) and pass that information :: along with the size of your graphics memory to /proc/mtrr and tell :: /proc/mtrr that it's write combining (the reason for mtrr support, :: mainly). :: :: With an AMD you may still need Alan Cox's mtrr patch, or 2.2.6ac1 which :: should include the mtrr support for AMD chips.

I try that, but it keeps telling me permission denied. I've even tried touch and vi, and it won't let me create the file (this is as root, of course). I guess I could try the ac tree, but I really prefer to stick with 'official' releases--it makes upgrading much easier (e.g., manual patch correcting is not my forte).
