Sadly, not quite.

The problem is that if the user is not using the mouse and kbd drivers
at all, but is instead using xf86-input-evdev, and no grabbing is done,
then all key presses end up going to the console.

Consider the effects of this when using things like alt-f1 or ctrl-c in
a program in X.

We have to keep the console itself from getting the events in question,
which means either unbinding the kbd interface, or some other sort of
grab, otherwise xf86-input-evdev is completely unusable for keyboards.

Grab support was my initial approach to the problem, in hindsight it
wasn't the right one, but it worked, and it's still needed for the
multi-seat people.

Ugly, but it works.
