NM finds all devices in HAL with the capability 'killswitch', and polls
them every 6 seconds to find out if any of them return 0 for GetPower.
If any do, it assumes rfkill.  Are you sure NM is allowed to talk to HAL
on your distribution?  Some distros like Debian use different D-Bus
permissions styles, and if those are wrong in
the /etc/dbus-1/system.d/NetworkManager.conf, NM may not be able to talk
to HAL and get the killsiwtch state.
