Ditto the "tablet mode" of some devices such as the Thinkpad X41, or the newer Lenovo Yoga, which should have their keyboards and touchpads disabled. If we used something like UPower to enable/disable those inaccessible devices, we'd need a way of enumerating which devices won't be accessible in those modes. Turning them off and back on should be easy enough.
