What I had im my mind behind "closing the lid" is the fact that 
closing the lid leads to suspension of the system.

What you propose seems a bit drastic to me as it makes the system 
nearly unusable for many people (that would want network or bluetooth 
keyboard). Also, you missed the cardreader (controllable via 
/sys/devices/platform/eeepc :)).

If we want to controll the power of all devices that can be 
controlled, the keyboard would fill with shortcuts.

Related, I recently added "options usbcode autosuspend=0" to 
/etc/modprobe.d/local as suggested by powertop. The bluetooth device 
is still powered upon activation, though 
(/sys/devices/usb/4-1/power/level is "on" and should be "auto").  
Perhaps this could be corrected in the script. The tricky part is 
getting the device address. Hardcoding "4-1" seems bad, although 
tempting, as the device is built-in and should not change its 
address... But on another model it could be different. *sigh*
