On PPC slot 1 is occupied by the VGA adapter, while slot 2 is the IDE controller, so we'll need to make some more complex changes here. We're gonna need to change this for every other arch too, in fact it looks like it probably differs for each '-M' arg value too :-( I'm wondering whether we should just have a separate method for each combo rather than trying to make one method do everything.
