I've been looking around my installation of Panther 7B21. In /System/Library/CoreServices/BezelUI/Images are the images used for things like the Airport menu status and a few that I've never seen before called: kbdConnect.png, kbdDisconnect.png, mouseConnect.png and mouseDisconnect.png. At the moment they don't seem to be ready (they just consist of the required text version: "Keyboard Connect Image" for example). Perhaps these are for some new menu status displays for a wireless keyboard and mouse?
