IIRC, the radeon driver still uses AGP writeback. This doesn't work reliably on my system and I disabled it in my local tree. Some people (including myself) have been thinking about an efficient algorithm to detect unreliable writeback, but AFAICT nobody came up with anything yet (at least no implementation). Should we just disable it for good?
