I think I misunderstood the assigning of a device to a seat.
The creation of a seat is not done by the udev rules, what I assumed first,
but only some properties (tags) are set, like ID_AUTOSEAT, SEAT and
ID_FOR_SEAT.
It's up to the programs who controle the sessions to create a real seat.
This is right?

What program is doing this now? Indeed gdm?
