I have two dells, for the bluetooth it actually unplugs the USB device,
i.e. i guess it powers it down.

The wireless (ipw2200 here) seems ot have a 'hardware radio switch' that
the driver is aware of, if its off sometimes you'll see info in dmesg
about it when you try to do things.

Fn+F2 does both at the same time.
