Have you rebooted without the Lubuntu disk in ?
Do a PRAM reset, maybe the hostname is stored in there.
Will do that now. Can I type "reset-all" in Open Firmware?
scutil --set HostName name-of-host

Then that's a problem with the DHCP table of your router.
Mine turns into a BlackBerry when I connect it to the network at work. I'd imagine that just rebooting your router would fix it; I doubt that you need to mess with the firmware.
