[fso/openmoko-panel-plugin] headset button?

[arne anka]

while playing around with the wired headset, i noticed, that apparently  
the plug in of the headset does not cause the gsmheadset.state to be  
loaded.
further investigation turned up that openmoko-panel-plugin in he category  
"buttons" offers to handle the headset -- looks good, but ...
there's nothing to be configured -- just "[] handle headset".

well, what does "handle" mean? shouldn't there be something to be done? i  
for one would like to switch alsa states upon plugin / oout.
