The /etc/start_if.* files are called pccard_ether which is called from
devd. It should run automatically when a card in inserted or when
detected at boot time.

I have the following in the start_if.wi0 in my default profile:
ifconfig wi0 ssid "" wepmode off

In my home profile I have:
ifconfig wi0 ssid "jt843kf" wepmode on weptxkey 1 wepkey 1:0x1234567890
(My home system runs WEP and does not broadcast a beacon.)
