I've been using radeon KMS on my PowerBook ever since I got it working
initially about 1.5 years ago and fixing issues as time permits.
The major outstanding issues I'm aware of are:
* The uninorth AGP driver doesn't allow AGP transfer rates beyond
1x to work reliably with KMS. Benjamin Herrenschmidt (CC'd) was
working on a fix for this, any progress Ben?
* Come to think of it, the OFfb handover probably only works for
me thanks to a patch "drm/radeon: Add early unregister of
firmware fb's" by BenH. Ben/Dave, what's the status of that?
* LVDS backlight control was only added for 2.6.38, and some
concerns were raised about the prerequisite backlight
infrastructure changes, so I'm not sure if it's staying in for
2.6.38 final.
* No suspend to RAM support yet. Suspend to disk seems to work
though without AGP, I have some hackish fixes for it to work
with AGP as well that I need to clean up and submit.
* Various endianness issues in the Mesa drivers.
