patch

obsolete

>Once the lid is closed, the keyboard event listener is set up to open the lid
>for us on keyboard events. With the right sequence, we can trigger the
>listener to be added to the list multiple times, triggering an assert in the
>list test code (or an infinite loop in the 1.8 branch).
>
>Conditions:
>* SW_LID value 1 - sets up the keyboard listener
>* keyboard event - sets lid_is_closed to false
>* SW_LID value 0 - is ignored because we're already open
>* SW_LID value 1 - sets up the keyboard listener again
