wpi0: radio is disabled by hardware switch

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
on a laptop with a  wpi interface, dcpcd brings automatically the interface
up, which leads to an endless stream of "wpi0: radio is disabled by hardware
switch" on console when the radio is turned off.

Is there a way to get status and notifications (other than watching dmesg) 
of the radio hardware switch, in order to e.g. enable or disable
wpa_supplicant and dhcpcd on the interface when the switch is used to turn
the radio on or off ?
