Then, my question is: can we assume, with xserver 1.8 and later,
xf86WcmInit (the device initialization routine) will only be called by your
libudev input-hotplug mechanism? Or in another phase: do you still allow
users to define input devices through xorg.conf?

If xf86-input-wacom will only be Init'ed by libudev input-hotplug, I can
"fix" my driver by creating all devices inside the Init.  Then the driver
will cleanup itself in UnInit.  I think I like this approach if you guys are
willing to take the risk of Wacom blowing up the server :).
