detecting tablet mode

[Marco Martin]

debugging a bit what happens currently on my machine, i don't seem to
have any event device which libinput_device_switch_has_switch,
however, when i flip it, i do get an event, but oddly from the event
device called
"intel virtual button driver" and i get a key event of id 240.
do you think it's a kernel problem and can'tbe made work on our level?
I can also try to do the patch blindly, but how to test not having the
proper hardware support? (on a running kwin, i know autotests have a
fake libinput that injects events)
I wonder on how many devices thoise events will actually work as intended...
