Either closing the lid, or using the menu option. The green sleep LED is 
lit during suspend. The machine does not boot and resume as it would for 
hibernation.

The sound module will not unload because Gnome desktop holds it open for 
sound events. I can log out, go to a text console, log in, remove and 
reload the sound module, switch back to GUI and log in, but that's not 
much of a resumption of my previous tasks.
