        src/sys/arch/x86/x86: genfb_machdep.c

Log Message:
Unfortunately the current MTRR code can't grow an existing WC mapping, and
since we don't know the total framebuffer size setting up an MTRR here
would prevent X from creating a larger one later.

Instead map the framebuffer with BUS_SPACE_MAP_PREFETCHABLE and hope that
PAT is supported.
