Modules/Ethernet setup

[Paul M Foster <paulf@quillandmouse.com>]

When I was installing Deb 3.0r1 on a new machine, I couldn't find what I 
thought was the right module/driver for the ethernet card, so I just 
skipped it. Later I found the right driver. I can get the card up and 
working. Manually, I can do it this way:

modprobe natsemi
ifconfig eth0 inet 192.168.10.2
route add default gw 192.168.10.20

However, I don't know how to integrate this with the Debian 
/etc/modules/* and /etc/modules.conf. Can anyone tell me what files to 
create and with what parameters?
