Actually, what would be a better interface? 

I wonder why it is not like this:

/sys/power/state 
	no change, works with and without opportunistic suspend the
	same. Ignores suspend blockers. Really no change. (From user
	perspective)

/sys/power/opportunistic
	On / Off
	While Off the opportunistic suspend is off.
	While On, the opportunistic suspend is on and if there are no
	suspend blockers the system goes to suspend.
