Is the mtrr code supposed to work properly for Athlon (Model 4) in
kernel 2.4.7?
I still get mtrr errors/warnings.

Mismatched mtrr warnings indicate bios writers who cannot read
specifications. The kernel will fix up after it

This does not surprise me. In fact, I need to check Tyan's web site for
a BIOS update.

I also get this message:
Jul 29 03:33:00 keroon kernel: mtrr: type mismatch for f8000000,4000000
old: write-back new: write-combining
This happens quite often, especially with the agpgart and NVdriver
modules.

iirc, this is a problem with the nvidia module, and there's nothing
the kernel can do about it. Complain to nvidia.

If I knew who to complain to, I would. I used to have a contact there,
but I seem to have lost his e-mail address. :(
(BTW, There's no update to the Tyan [Pheonix] BIOS as yet either.)
