I have two buttons marked with memory and disk pictures. When I press the 
first one HAL emits "sleep" button event, for the the second one HAL emits 
"hibernate" event. I am using KDE4 and neither works :) According to KDE4 
developer, they implement "suspend" button as suspend to RAM. Just trying to 
clarify which key this should be and whether HAL should be fixed.  (I opened 
bug report for KDE4)

I wonder, who is supposed to act upon it? Is there any generic user space 
agent who implements video output switching?

Ditto. Theoretically Toshiba even supports turning off radio via HCI, but it 
is again not clear who should actually initiate it.
