what can i do to help?

i just tried out 2.6.27-rc4, unfortunately without success.
here are my settings again,
if you need more info, just tell me.
as you can see, the mtrr size values are complete nonsense.
the framebuffer should be at d8000000.
i am unsure if this is the fault of the kernel or the bios.
or should the MTRR_SANITIZER resolv all broken bios issues?

please boot without mtrr_chunk_size=512m
and put debug in your command line
# cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size=198656MB: write-back, count=1
reg01: base=0x80000000 (2048MB), size=197632MB: write-back, count=1
reg02: base=0x100000000 (4096MB), size=197632MB: write-back, count=1
another case of crazy size in /proc/mtrr
it is E5420, maybe mtrr code has problem to handle that cpu?
