Comment (by kvdman):

 Seems this happens under Ubuntu 11.04 on Macbooks too.

 "MTRR setup doesn't work/happen. I assume this is due to the MacBook using
 EFI (well, an Apple variant of it) with a BIOS emulation. I manually set
 the two areas marked as prefetchable in lspci to write-combining in
 /proc/mtrr. This seems to help a bit against some of the really slow
 framebuffer updates."
