5.9 ghz support in the USA?

Quite a while back, the FCC made it possible to use a few channels more at 5.9ghz. The regulation is here: hp/https://docs.fcc.gov/public/attachments/FCC-20-164A1_Rcd.pdf

I am curious if this made it into the regulatory database, and does it work on any of the chips in the latest release?
