I'd suggest installing the PAO distribution from http://www.jp.freebsd.org/PAO/ to add some extra functionality. > I'd like to be able to use the ethernet card in three different situations. > First, I'd like to be able to use it as the only network interface on the > machine to access a stand-alone LAN (of about 5 nodes).

Leave it out; the pccard_ifconfig option takes care of running ifconfig aginst the card at insertion time. > Second, I'd like to be able to use the ethernet card to access the local > LAN while using ppp to access the rest of the Internet.

You'll need to add a net route for the LAN and anything else that's directly reachable that way, then set the PPP link as the default. > Will I need to statically define the other nodes in my LAN?

Set the default route as your router in this case.
