Thank you Brian -- this is exactly the information I was after. Much
appreciated, once again!
To get out of the situation I'm in on those two machines, I just need to
hand-craft the interfaces file to something like what you have above,
with appropriate device, ssid and WPA password values substituted. For
these PARTICULAR systems, firmware doesn't seem to be a problem.
