CVS commit: src/sys/arch/x86/x86
Module Name: src
Committed By: jmcneill

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.
