The problem seems to be that there was a series of security problems with the kernel module and it was dropped from the upstream kernel:
http://dri.freedesktop.org/wiki/ATIMach64/?highlight=%28CategoryHardwareChipset%29 so I think what needs to happen until someone fixes the kernel is to remove xserver-xorg-video-mach64 from xserver-xorg-video-all, so that it doesn't get installed; this gets you fallback that seems to work OK - except it can't detect multiple monitors; so it works OK on the LCD of this laptop and it works OK if I plug an external monitor and boot with it; but it can't switch between them.

I just upgraded that server from 12.04LTS Server. Before the upgrade, it had worked fine using startx to boot an instance of X for doing maintenance. Did a release upgrade (today) to 14.04 and it's now broke. XLog has that same exact message. Diving into it right now to check it out (see why it broke).
