Indeed.  And it seems that open events aren't counted when the Eee is 
suspended at the time, so you can't assume that odd/even implies 
open/close.  It seems that you can, however, look in 
/proc/acpi/button/lid/LID/state to get the current state.  So I've 
added this to my lid.sh:

# Ignore lid-open events
case `cat /proc/acpi/button/lid/LID/state` in
open)  exit 0 ;;
close) ;;
*)     # exit with a warning message maybe?

I think that the main case to worry about here is where you close and 
then open before the suspend has actually happened.

I would also like to do something about closing the lid after you've 
initiated a shutdown.  I think that there should be no suspend so that 
the shutdown can complete.  Is there a good way to detect that shutdown 
is in progress?

Cheers,  Phil.
