As the system puts a (uint) following the description when the modinfo command 
is used, the one above is redundant. Replace it with (0,2-5) instead. I have no 
idea why there is a hole in the debug levels, but I hesitate to close it. Also, 
send patches to John Linville with Cc to wireless.

Thanks for doing this. I'll sign off on it when you send V2.
