First and foremost, read /usr/src/linux/Documentation/mtrr.txt.
It'll tell you everything you need to know to get mtrr working (it really
does seem to make a difference in X on my PPro).
Basically, I've got a line in my rc.local which does something to
the tune of:
echo "Setting MTRR Optimization..."
echo "base=0x80000000 size=0x200000 type=write-combining" > /proc/mtrr
Where I've got a 2Mb video card, and X tells me that my card is
using base 0x80000000.
