AccelMethod "XAA" no longer seems to do anything. Whether it's there or not, this is in the Xorg.log:
(II) RADEON(0): EXA: Driver will not allow EXA pixmaps in VRAM
(...)
(II) RADEON(0): Setting EXA maxPitchBytes
(II) EXA(0): Driver allocated offscreen pixmaps
(II) EXA(0): Driver registered support for the following operations:
(II) Solid
(II) Copy
(II) Composite (RENDER acceleration)
(II) UploadToScreen
(II) DownloadFromScreen
But there are no odd allocation errors, and it seems to work as well as it did when I was using XAA. So it seems solved.
Looks like it's been solved one way or another.
