Not that I have much credibility to be talking here, but as a nouveau
user with a problem setup where I cannot seem to find anyone to help
[1], I wonder if getting support for the absolute latest GPUs into
mainline perhaps should not be the highest priority.  Also, have you
considered the possibility that taking longer for code to hit Linus'
tree would have the effect of increasing your tester base for
drm-next?  If I had a new video card that was giving me a blank
screen, I would certainly be ready to try a testing kernel tree if I
thought it would get me some level of functionality.

Luckily my problem is not a showstopper, and mainly prevents me from
using my second screen, but creating that bug and posting to the
nouveau mailing list did not get me much help in actually fixing the
problem.  This is despite the fact that I was quite willing to try the
nouveau kernel tree, which unfortunately did not help.
