I don't really know about this one but I don't any changes are needed in
your kernel config.  You must have the right driver compiled in as it
recognizes one card.  If the cards aren't plug-n-play, are you sure both
cards are set up to use different interrupts and memory areas?  Are both
cards seen in your dmesg output?

man rc.conf and man dhclient.  You use rc.conf to specify settings for each
NIC and dhclient will get setup info from a DHCP server.
