No, upstream doesn't solve anything. Upstream just dropped all we need to 
get DRI working on BSD platforms - XAA, EXA and DRI1 and switched to 
newer (Intel specific) UXA and DRI2. UXA itself doesn't need any support 
from kernel to work, but is slower and isn't reallysupported by upstream 
AFAIK.

(FYI, I don't get perfectly usable 2D display with my 965GM on DragonFly, 
too many artefacts to be usable at all ;).

As far as I understand it, you need to implement at least GEM in the 
kernel to make DRI2 working. KMS isn't must be for now, but upstream will 
drop user mode switching as well soon.

AFAIK both OpenBSD (owain@) and FreeBSD (rnoland@) are working on getting 
GEM into their drm drivers. But nothing is public yet.

Btw, I'm not against getting 2.8.0 into pkgsrc, it _might_ be already 
better than 2.7.1 for some users (with newer hardware) even on BSDs. But 
we certainly must preserve 2.7.1 as well.
