This seems to be fixed in current Gutsy. The problem with Clone mode is still there but this could be fixed through adding something like that to /etc/gdm/Init/Default:
#disable lfp if external monitor is connected
if xrandr | grep -q "VGA connected"
then
xrandr --output LVDS --off
fi
Compiz works but it is very slow on 1680x1050 screen. Maybe it is fault of the weak i915 chip.
