If you mark the interface down the radio should be turned off.  I can't tell 
if you're asking for a hookup to a button on the laptop.  Some Atheros-based 
cards have an rfkill input via a gpio pin that's hooked to a switch on the 
laptop (e.g. IBM T40*).  This mechanism isn't yet in the ath driver but 
should be there soon (someone is testing the changes and they'll be rolled in 
once we know they work).
