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.
