Source of regulatory information

I am working with the folks that are reverse engineering the Broadcom wireless driver for Linux. Part of the job involves adding a software MAC layer to the ieee802.11 code. At present, each of the wireless drivers handles its own regulatory/geographical information. This leads to such absurdities as b/g drivers doing active scans for channels 1-14 everywhere in the world, even though channels

12-14 are not allowed in the US, and AFAIK channel 14 is only allowed in Japan.

I have googled for every keyword I could think of, but have not found any sites that spell out the a/b/g channel and power restrictions in force throughout the world. Most of what I have found is contained within the source code for the Intel ipw2200 driver, but that is given as obscure codes with little information regarding the regulatory jurisdiction. I also have the IEEE public documents, but they don't help much. Is there a site, or set of sites, the can provide this regulatory information?

Thanks, Larry
