This looks similar, the aperture allocated by the BIOS looks to be 16MB
but the card really wants 32MB so there simply is not space.  This will
prevent DRI from initialising and that in turn stops compiz from being
used.  You might want to check if there are any aperture options in your
BIOS and see if they let you make the space larger.
