To sum this up then (as I understand things):

1. I am the system administrator (root);
2. 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.

Thanks again,

Chris
