You may or may not have fixed this, but I just recently had this problem on Slackware 11 (kernel 2.6.17.13) with a Graphire4. I fixed it by getting the 0.7.6-1 production drivers, compiling, and installing. I posted this hoping to benefit someones sanity, as I know finding a solution can be frustrating.
I had this same issue. I would do a:
Code:
wacdump /dev/input/event#
and the kernel driver was reading my wacom as it should (all coordinates, switches, and pressure). The X driver on the other hand was not reading at all. I'd point to the appropriate device in xorg.conf, but no dice. Why? I haven't the faintest idea, but an upgrade worked. Maybe the kernel driver and the x driver weren't communicating properly (thats a left field guess).
This is the link to the Driver I used.

Make sure you compile it using the X11 SDK.

And follow this guide, it's for Ubuntu, but it works.

Once you've untar-ed the driver and installed the SDK, it's a ./configure, make, make install (or checkinstall if you want to keep track) routine to get it installed. Configure your X11 config file, per the directions in the Ubuntu guide, reboot your machine and re-enter X and it should work.
Good Luck.
