You should use /etc/pm/sleep.d for these purposes. For example, create a
new file in /etc/pm/sleep.d/10key_issue with this content:

#!/bin/sh
case "$1" in
	hibernate|suspend)
		echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind
		;;
	thaw|resume)
		echo -n "i8042" > /sys/bus/platform/drivers/i8042/bind
		;;
	*) exit $NA
		;;
esac

Of course, you can replace the content with your needs.
Don't forget to chmod +x once saved.
