Pull up following revision(s) (requested by riastradh in ticket #911):
        sys/external/bsd/drm2/dist/drm/radeon/radeon_bios.c: revision 1.3
Fix two issues in NetBSD implementation of igp_read_bios_from_vram():
 * Allocate the correct buffer for the VGA BIOS image.
 * Abort if buffer allocation failed, not if buffer allocation succeeded.
Not directly tested, but I can't imagine this makes anything worse.
