This is a little out of my league, but I think you'll need to take a look at olpc-kbdshim [1] so see how things are currently triggered, in particular the olpc-rotate script. If you want to pickup aspect ration changes on the Sugar side, perhaps hook a gtk.gdk.screen_get_default().connect('size-changed', <do something interesting>) callback intp the sugar toolkit. I've implemented something simple like this in the Moon activity, so that it uses different layouts for landscape and portrait screen orientations [3].
