I have a laptop with external monitor in extended desktop mode, which
in principle I assume is a similar situation.  I just use System,
Preferences, Monitors to setup the resolutions and these are
remembered for me with no problem.  Using 10.04 but the same thing
worked fine in 9.10, though I think it was Displays rather than
Monitors in the menus.
