I am not rewriting this driver in the immediate future, thus you need to find 
out what is wrong.

As I said earlier, your error certainly looks like a privilege problem. Adding 
to what I posted earlier, I get

finger@larrylap:~> iwconfig wlan9 essid test
Error for wireless request "Set ESSID" (8B1A) :
     SET failed on device wlan9 ; Operation not permitted.
finger@larrylap:~> sudo iwconfig wlan9 essid test
finger@larrylap:~>

As you can see, my unprivileged version gets exactly the error message that you 
reported and the one as root works.
