I got this in dmesg with 2.6.14-rc7 when I restarted X with
ctrl-alt-backspace due to a lockup. Is it a kernel bug or an X problem?

Is that a typo (2.6.14-rc7 or 2.6.15-rc7) ?

I see that always when starting X:
mtrr: 0xe1000000,0x800000 overlaps existing 0xe1000000,0x400000

Same here
mtrr: 0xd0000000,0x8000000 overlaps existing 0xd0000000,0x2000000

It appeared around kernel 2.6.14

And I've built and ran virtually every kernel from 2.6.14 to 2.6.15-rc7
without encountering that message. Ati 9200SE card, 128 megs of ram.
