myth12 linux # cat /proc/mtrr
reg00: base=0x000000000 (    0MB), size=  256MB, count=1: write-back
reg01: base=0x00c000000 (  192MB), size=   64MB, count=1: uncachable
myth12 linux #

Seems that maybe this machine really doesn't have an MTRR at e8000000.

Are MTRR's necessary? This machine ran a much older kernel - circa
2.6.19 - until I tried to upgrade the xorg server. Possibly I was
never using MTRR and having it turned on at all is a mistake?

Thanks,
Mark
