On my system - hal knows about the killswitch:
$lshal |grep -i killswitch
info.addons.singleton = {'hald-addon-rfkill-killswitch'} (string list)
info.capabilities = {'killswitch'} (string list)
info.category = 'killswitch' (string)
info.interfaces = {'org.freedesktop.Hal.Device.KillSwitch'} (string list)
info.product = 'phy0 wlan Killswitch' (string)
killswitch.access_method = 'rfkill' (string)
killswitch.name = 'phy0' (string)
killswitch.state = 1 (0x1) (int)
killswitch.type = 'wlan' (string)
and NM also wrote to syslog saying it found the switch, and other
stuff when the switch is turned on and off:
#grep kill /var/log/message
...
