   It seems that no dri device major number is defined, the following patch
   should fix that as it appears to be MI .. mrg?

yeah, there's a problem but i was getting confused with it.

no, this patch is wrong.  drm major is not 195.  it is 180.  eg:

sys/conf/majors:device-major drm             char 180                drmbase

the problem is that ew call it "drm" and use "dri", and this confuses
the MAKEDEV* code.  but patching MAKEDEV.tmpl to know about this still
gives me errors and i haven't gotten around to solving it.

the patch below is what i have so far, but doesn't work, if anyone
really wants to figure it out for me...


.mrg.
