I am using a valid (albeit deprecated from 2.6.31) method to tell the wireless infrastructure that I want the regulatory domain set to GB; 3. GB is a valid code; and 4. the wireless infrastructure sets the regulatory domain to CN. 5. in 2.6.30, the wireless infrastructure does what I (the root user) tell it to do. That's a regression in my book. Oh well! I do have the iw and crda applications installed, so I've taken that route of setting the regulatory domain to GB. Interestingly, if I make no attempt to set the regulatory domain at all, it get sets to World and CN never comes into it. It's only if I try to set it to GB via the module parameter that it gets set to CN. To me, that seems broken.
