Ah, splendid. Seems you're way ahead of me :)

I'm afraid I don't quite understand this. AFAIUI, the input classes
will look directly at the udev properties, and the x11_* properties
will be dropped completely. But Peter's proposal [1] already has
MatchIsKeyboard, MatchIsPointer, MatchIsJoystick, and the like. So am
I missing something, and this isn't enough for some reason?

(For this particular bug we should probably not do the
"evdev-catchall" thing, though.)

Thanks,

Martin
