Of course you can.  Linux is designed to handle multiple networks
(really any OS is, but...).

The caveat being that the networks need to be different IP subnets.  You
can't have both networks in the '192.168.0.X' range.  (Well you can, but
for simplcity's sake, let's not.)

If one network is 192.168.1.X and the other is 192.168.2.X, then you
shouldn't have any trouble routing between them.

I guess the main question here is which one will be the default gateway
to the internet?  I would make the 'wired' one the default for internet
traffic, then if that goes down, you can have all internet traffic fail
over to the modem (using a higher preference) if you want.

Make sense?
