Indeed it was. The kernel was upgraded in the process from 2.6.16-em64t-p4 to 2.6.18-3-amd64. Rebooting back into the old kernel has given me back network, but the printer still not recognised as a device on usb0. (I got your mail too late to try ifdown)
Have a look at the output of lsusb and just check it can see something that at least looks like it is your printer.
Then tail messages and just see if sensible things happen when you unplug and replug the printer. You should at the very least get something like a message from the usb subsystem saying that a new device is trying to register followed by usb lp0 popping up saying it has found a device (which will have matching vendor and product id's to what you saw in lsusb.
