Ok, and here's what I consider to be the "final" version for now. It
cleans up the event handling (it turns out that the event value
corresponds to the SN00 value required to call the corresponding
function) and adds support for the external switch to flag the devices
as being in HARD_BLOCKED state. Tested on a P series (remotely), if
someone could check it on a Z and ideally a TT, that would be great. I
think it's otherwise basically complete for keyboard and rfkill
handling.
