 	This enables some cheesy code to save the last PM event point in the
 	RTC across reboots, so that you can debug a machine that just hangs
 	during suspend (or more commonly, during resume).
 
+	To use this debugging feature you should attempt to suspend the machine,
+	then reboot it, then run
+
+		dmesg -s 1000000 | grep 'hash matches'
+
+	CAUTION: this option will cause your machine's real-time clock to be
+	set to an invalid time after a resume.
