Does he have onboard 10/100 and is it a Broadcomm chip?  Seems I
remember reading that the mac addresses for onboard stuff could be
changed...somewhere.  I thought it interesting at the time but right now
I can't remember exactly what the context was.

Check the route via the route command and make sure he has the right
gateway.  Don't depend on the config files, use "route" and see what's
there from the command line.
