By the way, for what it's worth I think it's a very bad idea to hot-plug PS/2 keyboards. The hardware may be better nowadays, but back when I was a PC repair tech I made very good money replacing the fuses on motherboards that would blow because someone hot-plugged the keyboard.
That said, there are times when it happens, and many people don't see any problem with it.
