The clue was lines saying the DRI2 and DRI were unsupported by screen0,
therefore AIGLX failed to start.

It seems a lot of breakage will be fixed in the forthcoming 2.6.30
kernel. The new Xorg drivers are incompatible with the drm and radeon

Also, it appears that rebuilding the drm and radeon modules has solved
the problems of others so I may try that too:
