Unfortunately, the i810 driver is very old. We are now reaching intel
2.3 soon and the code changed a lot since then. Is there any chance you
try a more recent Xorg from testing or unstable? Anyway, with recent
drivers, you should probably switch between clone/single display using
xrandr anyway since hotkey-switching often does bad things in the back
of the driver.
