Good catch.  I thought it was documented already.  Perhaps it got
lost.  In any case, I think it would be good to mention why someone
might want to turn it on.  Perhaps something along the lines of:

	"This increases power-consumption.  On the positive side, it
	 reduces interrupt wake-up latency, which may improve
	 performance in certain environments such as networked
	 servers."
