<pre>Yep, that's it.
I tried hitting all the keys and then again while holding "Fn" key. Fn is a
Razer hardware modifier that is not visible to the kernel. When holding it, it
turns off all the keyboard LED's except for the function key row and the arrow
keys. For the vast majority of these keys, Fn+key causes the secondary label
key press to be sent. For example, there's Fn+F6 that sends Media Play/Pause
that's sent on event10 (the main keyboard device like any other key press).
There's exactly one key on the internal keyboard that maps to the first
internal keyboard device (event9 below): Fn+F4 (switch video output). By the
udev rule (because there's no way to disambiguate them) this is the one that is
associated with the lid switch in the debug output. If I press Fn+F4 after
opening the lid, the lid switch open event is written:

[close lid, suspend, resume, open lid, hit Fn+F4]

Living with hitting Fn+F4 after opening the lid as a workaround goes is fairly
undesirable because hitting that key causes the internal Intel GPU to go
through the act of switching through all external video output ports to find an
external monitor. This causes the internal display to be blank for ~3 seconds.
So, how do we have the second keyboard that has this label be associated with
the lid switch, also? It seems that the video switch keyboard is always getting
enumerated first.</pre>
