I tested your iwconfig statement using kernel 3.3-rc5. It worked. Then I 
downloaded a fresh copy of 3.2.9 and built it. It also worked. I have no idea 
what is wrong on your system, but it appears not to be the kernel, but something 
in your user-space tools. My tests were done with openSUSE 12.1.
