One thing has nothing to do with the other :)  transmitter blocked == energy
emission forbidden.  I say it like that so that people don't think it is
okay to just block data transmission and leave a carrier still being
transmitted, or whatever.

Remember, rfkill is *generic*, it goes well beyond WiFi.

Mess? How so?

Anyway, I have been looking at everything that includes linux/rfkill.h.  I
cannot trust every current in-tree user of rfkill to be shutting down the
devices on suspend by just a quick look at their drivers,  I just don't know
enough about drivers/net/usb/hso or arm/mach-pxa/tosa.  I can't even be sure
about rt2xxx USB by just looking at the code...

So I will ask their maintainers first, instead of trying to guess.  Lets see
what answers I get.
