Another thing worth noting is any virtual interfaces created on eth1
will not work for some strange reason.
However, I looked on one of our firewall boxes, which is separating
two networks, routing, and filtering packets. It has one IP address
on either network. This is working fine:

The eepro100 module is compiled into the kernel.
Thinking back, last year I set up some ISP2150's (virtually the same,
but 2U high) that had one onboard NIC and we added one PCI eepro100
into them. They worked fine, as we had one on a 213.206.4.xx address
and one on a 10.0.0.x address; on totally different switches.
