Nope,  I've had two NE2000 cards working in an old machine once.  First I'd
take out eth0 and see if the system detects the other card as eth0.  Just to be
sure it is working,  and not conflicting with anything else.  I think I
compiled the kernel with the NE2000 drivers as modules and did something in
/etc/conf.modules,  mostly the Redhat network config did it for me.  I recall I
wasn't able to get the lilo append=ether statement to work.  Sorry my
recollection is so fuzzy.
