[Techtalk] MTRR info please

[Patricia Fraser]

Hello all,

recently (since using kernels 2.6.10 and above) I've been getting a "no 
more MTRRs available" message at boot time, so I did a bit of googling 
and I'm not really a lot the wiser. My /proc/mtrr looks like this:

reg00: base=0x00000000 (   0MB), size= 128MB: write-back, count=1
reg01: base=0x08000000 ( 128MB), size=  64MB: write-back, count=1
reg02: base=0x0c000000 ( 192MB), size=  32MB: write-back, count=1
reg03: base=0xe8000000 (3712MB), size=  64MB: write-combining, count=1
reg04: base=0xe8000000 (3712MB), size=  64MB: write-combining, count=1
reg05: base=0xe0000000 (3584MB), size=  16MB: write-combining, count=2
reg06: base=0xe6000000 (3680MB), size=  16MB: write-combining, count=1
reg07: base=0xe4000000 (3648MB), size=  32MB: write-combining, count=1

I've looked at the BIOS, and there doesn't seem to be much I can do to 
tweak what memory is set aside for graphics. Will it maybe make a 
difference if I set X up to use less video ram? I'm hoping for 
something that will use a bit less of my poor CPU, which seems to be on 
99% more of the time than I'm happy with.

Any clues where I could go for more reading?

Cheers,
