error.

Kludge around linux bug and turn off write-through and cache-disable bits

When mmaping the PCI device, the kernel turns on the write-through and
cache-disable bits in the allocated PTEs. This disables write-combining mode
and dramatically reduces write bandwidth to the frame buffer. While that
should be fixed in the kernel, we'll kludge around it here by using mprotect
to rewrite the PTEs and get those bits turned off.
