Seriously try one of the air remotes. It's like a gyroscopic remote and it works way better than I ever thought it would for controlling a mouse cursor. They're very cheap too, the one I have cost 30bucks, it can sense if you have it on the keyboard side or the media side facing up and disables the other sides buttons, deactivatable backlight on the buttons, and rechargeable battery, although it lasts for weeks without charging.
