Btw, for future, the commit 85568da345d4348f33c69043c9bc4e78ad819706 ( http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-jaunty.git;a=commit;h=85568da345d4348f33c69043c9bc4e78ad819706 ) is not included in 2.6.29.
Here's the current 2.6.29 head which also doesn't include r600 drm stuff; http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=tree;f=drivers/gpu/drm/radeon;hb=c31f403de62415c738ddc9e673cf8e722c82f861
So dropping this after 2.6.28 will cause (currently) r600 exa to fail.
