Don't Hotswap PS/2

When my parents brought home my school computer, my brother hooked it up to the Internet, and this became the server for http://roadtrip05.dyndns.org. When I came home last yesterday, I noticed that he had neglected to plug in a keyboard, so i had no way of locally logging on to the server. I know that it is a big no-no to plug in a PS/2 keyboard while the computer is running, but I decided to risk it anyway. Needless to say, kernel panicked (first time I've experienced an actual kernel panic), and the server crashed. Luckily, no hardware was damaged, but Shaw did manage to change the server's IP address in the time that it was down. I've updated the IP address in DynDNS's records, but it may take a while to replicate through DNS hierarchy.
