Have drm running with my R630, but there is some type of performance problem
(i.e. slow windows).
Given that I don't have the time to work the issue right now, here is my
summary for those that want to give it a try.
If you start with drm git master 1) incorporate the local freebsd updates, 2)
incorporate the radeon updates from drm git r6xx-r7xx-support, and 3) add the
attached patch, you will have what I have.
For the video drivers, I have only tried the xf86-video-ati r6xx-r7xx-support
branch and not the xf86-video-radeonhd r6xx-r7xx-support branch.
There was a comment on radeonhd irc about backing out drm git
r6xx-r7xx-support commit for "R6xx/R7xx: pad VB age submission to 8 dwords",
for the performance problem but that didn't help me with xf86-video-ati.
