It appears that these cards are connected to the same Ethernet segment. 
That is a no-no.  The BSD networking system doesn't support multiple cards
on the same segment in the same machine. Routing becomes infinitely
complex in this scenerio; no one can tell just who (by hardware address)
to send the packet to.

Take one or the other out and you should be OK.  I'd suggest the NE2000 :)
