Thanks Dave,

I switched to the i915 kernel driver and still got the OOPS.
I also continue to get the overlapping mtrr message. I am currently
testing 2.6.13-rc2-git3. I have tried to run strace with hald, but
cannot reproduce the problem this way. I am not sure I am invoking the
command corrently. I have written to the hal developers, but have not
received a response yet. Here's the current output:

mtrr: base(0xe8020000) is not aligned on a size(0x3c0000) boundary
mtrr: 0xe8000000,0x8000000 overlaps existing 0xe8000000,0x1000000
