Similar MTRR issue here with a K6-III/450, which I noticed when the X11
server was no longer able to allocate/configure a MTRR. "cat /proc/mtrr"
shows nothing configured regardless of whether the X11 server is running.
I only see a diagnostic message to the effect of the MTRR not existing
when X11 exits.
Possibly significant: prior 3.X kernel versions would cause the X11
server to exit with a corrupted display after about 3-5 invocations.
Machine was otherwise usable, but had to reboot remotely to recover the
console display. The "no MTRR" issue in 3.1-rc1 has thus far meant no
display corruption on X11 server exit: have run "startx" at least 10
times since booting 3.1-rc1.
