The machine's gateway is aleardy there (last line of routing table). If
you want other machines to hit the internet through it, you need to do
something like ipfawm -F -a m -s 192.168.0.0/24 -d 0/0 and set the
gateway on the _other_ machine(s) to be this one's ethernet address
(192.168.0.1). Doing a route add 192.168.0.1 before the -net is good
juju but usually makes no difference for me.

cat /proc/pci might tell you more.

The RTL8029 cards suck, but suck consistently. What sort of serial
controller do you have?
