32-bit x86 kernels usually come in two flavours: with and without PAE
support.  The normal one is without.  The kernel with PAE support can

| [   42.397018] mtrr: no more MTRRs available

I wonder what that is about.  Can you tell me what /proc/mtrr says?

My guess is that all 8 MTRRs are being used and there isn't one free
for the video card's address range.
