"I recently (on a flight) I found out that when I boot with the hard-switch
activated, so turning off all wireless activity on my laptop, the state
is not correctly announced in /dev/rfkill (reading it with rfkill command,
or my own gnome applet)...
After turning off and on again the hard-switch the events were right."
We can fix this by querying the firmware at load time and calling
rfkill_set_hw_state().
