Thanks for retesting this on the latest kernel.  This driver has
actually graduated into the stock kernel.  I've added the
wireless people and the maintainers to the CC list.

So rfkill disable and enable cycling, has never worked on this chip?
Which chip is it?  Perhaps do an lspci -vv and a dmesg and attach
them to a reply email.
