DRM kernel branch, remember that KMS is off by default, for good reason -
For the xorg driver
For the next few weeks I'm going to be focusing on gettting the GEM/TTM
working with the xorg driver. So except alot of changes in the kms_branch.
I will make a announcement once I have DRI2 support going. Also Possible
are some changes in the drm-openchrome to handle any bugs encountered.

No problem. Recently I checked in a new date time stamp for the DRM driver
to see that the KMS/GEM work was only started at the end of february.

Even tho the goal right now is updating the xorg driver it would be a
waste of time not to write the code so it could just be dropped into the
gallium infrastructure very easily. I really like to see the xorg driver
be built from the gallium xorg state tracker :-)

Check out both branches above and test them on your systems. I need to
make sure no regressions happened. Also test out the kms_branch with the
mainline VIA drm driver to make sure that works. Ideally I like to push
out the xorg driver first so when the openchrome DRM kernel driver does go
main line it will be ready to go.
