   I've just installed a new build of -5, updated a few hours ago, that
   hang is now fixed on my i915gm laptop (mentioned earlier in this PR). I
   highly recommend installing latest xsrc and seeing whether that fixes
   the issue.

netbsd-5 (and -current) both enable VGA devices io/mem/bus-master
bits inside libpciaccess, so this should be OK now, even if the bios
brings it up disabled.
   
   (drm diff can also be found at http://netbsd.org/~jmorse/drm4.diff)

i'll test this shortly.  i think we need it for netbsd 5.1 as well.
