Looking at "auto_wep" in the Linux driver I don't like it. It breaks
some implicit features of the card that I like. That is if I'm reading
the code right.

You can tell the driver to do that.

You can run the Linux ACU on -stable or -current.

Mine does and doesn't require auto-wep that could trash the keys in the
card. I like the NVRAM key holding feature of the Aironet card so I
don't have to put my home/work keys in my /etc files. Also works across
Windows. I store my work key in the standard keys and home key in the
home key. You need 4.5-stable or -current. I put my laptop to sleep
change location and resume then my laptop connects to the network.
Here is my /etc/start_if.an0 where I think this functionality should
be put since then you can add any arbitrary scheme. I also have
stuff in my /etc/dhclient-{enter,exit}-hooks to do more network
configuration automatically since I'm to lazy to do it myself.
Note no keys are in this file since I don't have to have them there.
I did sanitize the SSIDs even though it doesn't really matter.
