KMS is a little tricky, but I've been starting to look at it.  If by
DRI2, you mean gem and/or newttm.  They are on my list of stuff to deal
with.  No matter what, I will have to pull code from a linux tree
somewhere as the basis to start.

It frustrates me, but their goal isn't to make things more difficult for
us (me in particular).  They (primarily Intel) is trying to simplify
their process for upstreaming to linux.  As changes to infrastructure
occur, someone has to back port those changes to git.  I don't have the
time to try and do it, nor do the folks from ATI/AMD or the Nouveau
crew.  Intel has by far the most people working full time on drm and X,
so they tend to get away with what they want to.  Given that git doesn't
match what is in Linux, it means that in order for anyone else to ship
code to Linux they have to rework it before sending it up, it is just
much easier on everyone if they do so.  Right now, Alex(AMD) and I are
doing a fairly decent job of staying in sync.  I think the same will
work for Nouveau.  Intel is just too chaotic, so I just try to sync up
with what they are shipping periodically.
