I use the {start|stop}_if.* files for my wi0 setup, my fxp0 too.

start_if.wi0:
#!/bin/sh
#/sbin/ifconfig wi0 up
/sbin/ifconfig wi0 wepkey 0xXXXXXXXXXXXXXXXXXXXXXXXXXX wepmode on
#echo "sleeping 15 seconds to allow time to associate..."
#sleep 15
dhclient -pf /var/run/dhclient.wi0.pid wi0

stop_if.wi0:
#!/bin/sh
/bin/kill `cat /var/run/dhclient.wi0.pid`


Sometimes, it seems that I need to uncomment the #'d lines in
start_if.wi0 in order to get dhclient to work properly.  

I created stop_if.wi0 after dhclient started consuming all CPU when I
removed the card.

This also allows me to change locations fairly easily by adding a case
statement to start_if.xxx so I can manually run it with an argument
telling it where I am and how to deal with the network there.

Be sure to use:
pccardd_flags="-z"      # Additional flags for pccardd.

in rc.conf.  It is now the default.
