drm/dri update

[Hasso Tepper]

Some comments after playing with it.

* I'd like to see committed into upstream, that would make reporting bugs 
  against upstream easier.
* Loading modules via loader.conf(5) doesn't work - no drm device is 
  detected. Btw, coretemp(4) has same problem :(.
* Anyone pinged LibMesa(-dri) maintainer regarding this tiny mklib fix? I 
  can't push it upstream. mklib mesa is using needs much more patching 
  than this little fix and I don't have time for that at the moment.

And just for info. There seems to be a lot of issues with i965 chips. I'm 
not sure which of these (and whether at all) are our problems, but I'll 
try to bug upstream about all issues.

Anyway, good work and please commit ASAP (both our CVS and upstream)! :)
