I'd concentrate on finding where your eth0 interface is being configured
from if it's not in /etc/network/interfaces. I think that whatever is
configuring it is doing something "bad" and messing the rest of the
system up with it. I'd add the proper eth0 section in the interfaces
file and go hunting in the /etc/init.d files for anything interesting
about routing, networking etc. I've got a similar set up with 2 cards,
cable modem, and a modem and I have the cards in interfaces and bringing
up ppp0 with pon works fine without disturbing anything.
