I'm sorry for the late reply, I don't read this list very
often.  But better late than never.  ;-)

Yes, it works on my notebook.  Actually I don't need opengl
because I'm not a 3D killer game player, and I think those
3D opengl screensaver modes are a waste of battery power.
But I tried to get 3D acceleration working anyway, just out
of curiosity.  :-)

I'm using RELENG_6 (about 6 weeks old), with the agp and
drm sources copied from a CURRENT source tree (8 weeks old).
Maybe those got MFCed to RELENG_6 in the meanwhile, I don't
know (I think Eric Anholt was planning to do that, but I'm
not 100% sure).  But back than I had to copy those -current
sources over.

Other than that, I use Xorg 6.9 and the standard dri and
opengl packages.  No special patches or anything.

I plan to update my notebook to a newer RELENG_6 soon
(maybe next weekend) and try to see whether it now works
without the -current bits.

Best regards
   Oliver
