I also experience this bug on ATI Rage Mobility M1 with a very similar XOrg.log. On lubuntu 14.04 it causes lightdm to enter an infinite loop, can't even login graphically. I think this is the corresponding upstream bug, which has been fixed. https://bugs.freedesktop.org/show_bug.cgi?id=70556 Could we get this package updated accordingly?
