Comment:

 To reiterate what I'm asking for from the kernel:

  * When entering "idle-suspend" mode, I want a lid close transition after
 the suspend to wake us and deliver the event to userspace so that we can
 turn off the backlight.
  * When entering "sleep" mode (through a power button press), I want a lid
 close transition to be totally ignored and for the laptop to stay asleep.

 Since both of these modes are just seen as a suspend by the kernel, we
 would need a signalling method for userspace to tell the kernel which type
 of suspend is about to happen, so that it can reprogram the GPIO lid
 transition triggers appropriately.

 I think this probably has to wait until 8.2.1, since designing and testing
 interactions between kernel and userspace tends to take significant time.
