I had the same problem upgrading from 7.2 to 7.3 . Switching to the
intel driver also 'fixed' the problem, but introduced a new one: I
cannot make the intel driver drive two independent heads (either with or
without Xinerama). I will submit a bug report (probably to xorg though)
when I have time - for now single head is fine. 

FWIW the 'i810' driver is the 'intel' driver at version 1.6.5. The
'intel' driver is the latest 'intel' driver at version 2.1.x . The
rename of the driver occurred when it moved to version 2.0.0 iirc. The
'intel' driver also knows about correctly setting video modes that
aren't present in the VBIOS, so hacks like 915resolution are no longer
required when using the 'intel' driver.
