Make this a CONFIG option instead of using another file.

Can be removed or moved to Documentation/networking/ somewhere if its really useful.

This can be removed.

Documentation/networking/ somewhere, but this documentation is not
relevant for the kernel.

Please consider using cfg80211 and new regulatory framework for this.
Then you can refer to iw:
http://wireless.kernel.org/en/users/Documentation/iw
Regulatory stuff:
http://wireless.kernel.org/en/developers/Regulatory
Also please read Documentation/networking/regulatory.txt

Please keep files in its own directory.

Ok well that should take a while..
