Hi Animtim,
I’ve looked to my xorg.conf and I don’t see anything special for the wacom setup for dual screens. All the relevant lines are commented out by hal.
Basically the thing is that I use the wacom device from time to time and I only use it on one of the monitors. I have a Tablet laptop where I squeeze my brain to produce “quality images” 
So the Graphire is a dust covered device latest days.
