I think I see the problem here ...

ipadress 192.168.1.1 with netmask 255.255.255.0 will make all adresses 
192.168.1.x accessible by the interface

ipadress 192.168.0.1 with netmask 255.255.255.0 will make all adresses 
192.168.0.x accessible with the interface (and NOT 192.168.1.x) (nothing 
meant for 192.168.1.x will even be sent out on that interface, so if you run 
tcpdump, that will suggest the card doesn't work)

(btw if the card doesn't work, tcpdump will STILL give output in most cases, 
and it will most likely look perfectly normal)

the pci thing you suggest simply determines which card is detected first, and 
so which card gets to be eth0 and work (because of the issue above)
