It turns out that both kinds have the same ID. I think one of them is a 
prototype, while the other is probably a production unit. Obviously, bitrot has 
set in while I wasn't testing. With the kernel driver, neither unit can even 
scan in the 2.4 GHz band. Using the latest version of the vendor driver, the 
production version connects with APs running WEP, WPA, or WPA2. The prototype 
can only handle WEP.

Obviously, I have some work to do. In the meantime, I will send you a tarball 
containing the vendor driver - privately so as not to spam the list.
