I can confirm too, using brandsnew "Microsoft Wireless Laser Desktop 5000" (just out of the store) on 8.10 (kernel 2.6.27-9-generic).
No action when hitting F1-F12 Buttons although xev shows that these generate events (F3 -> event.keycode == 69)
The 5 "Favorite" Buttons generate keycodes 192-196, all the other extra keys do not generate anything.
