Looks better than what I'm getting on 2.5.59:

curly:~# cat /proc/mtrr
reg00: base=0xc0000000 (49152MB), size=16384MB: uncachable, count=1
reg01: base=0x00000000 (   0MB), size=524288MB: write-back, count=1
reg02: base=0x800000000 (524288MB), size=262144MB: write-back, count=1

Yes, this is standard ia32 (P-III/Coppermine cpus), and hence the
numbers here are utter garbage.
