Wacom with Dual Head

[Chris Spencer <gmane.20.evilspam@xxxxxxxxxxxxxxx>]

I plugged in my Wacom Graphire tablet and, to Fedora's credit, I was 
able to use the tablet's basic mouse-like functionality. However, 
pressure sensitivity doesn't seem to work in the Gimp, and more 
importantly, the tablet to screen mapping is producing weird affects 
with my dual display setup (spanning desktop).  It's hard to explain. 
Depending on where I put down the pen, the tablet my map more-or-less 
correctly to both screens. However, sometimes about 2/3 of the tablet 
will map to the entire left screen with a 1" left margin, while the 
other 1/3 will map to half of the right screen with a 4" right margin.

Is there anyway to fix this? Are there any applications for configuring 
the tablet, or is the only way to edit an X config file? Any help is 
appreciated.

Thanks,
Chris Spencer
