Configure WEP on startup

[Christopher Rued]

I apologize in advance if this question has been asked and answered 
before, but I haven't really found a completely satisfactory answer 
anywhere that I looked.

My question is: what is the correct way to configure my wireless network 
card to use WEP and to obtain an IP address from a DHCP server at at 
startup?  What's the magic line to insert into rc.conf?

uname -a:
FreeBSD laptop.xsb-internal.com 5.3-STABLE FreeBSD 5.3-STABLE #0: Wed 
Nov  3 06:45:45 EST 2004     
root at laptop.crued.net:/usr/obj/usr/src/sys/GENERIC  i386

The closest thing I have found is 
https://cusg.eecs.berkeley.edu/~bira/freebsdwireless.html but this is 
for an older version of FreeBSD and it requires some weired hackery, 
such as inserting sleeps to (hopefully) allow the rest of the system to 
get to a point where wicontrol commands will work.  Also, it seems to be 
for an older version of FreeBSD and uses deprecated wicontrol commands.

(It would be nice if sysinstall would handle this).

Please include me on any replies, as I am not subscribed to this list.

TIA
