drmkms intel

[Robert Swindells <rjs%fdy2.co.uk@localhost>]

As an experiment I tried removing the BUS_SPACE_MAP_PREFETCHABLE flag
from calls to bus_space_map() in the intel drmkms code.

Stuff that uses render calls still doesn't work properly but it does
look slightly better, if I do a directory listing with using a TrueType
font some characters are correct.

Maybe there is still a difference in cacheable status of pages from
what they would be under Linux.
