wacom works with X, but gimp and xidump don't see it

Dear all,

I have a wacom tablet (Graphire, USB) and I managed to get it working
on Linux... yet I don't get the final thing right: pressure
sensitivity in the Gimp.

Here is what I have:
* AMD sempron
* OpenSuse 10.2
* NVidia FX 5200, dual monitor.
* The latest stable drivers from the linuxwacom project: 0.7.8-1
* One USB optical mouse
* A Wacom Graphire USB tablet

The tablet seems to function fine in X:
* It does absolute positioning, and because I have configured the
tablet with TwinView=horizontal, it changes screens without problems
* The tip, and two buttons on the side of the styles work fine
* The eraser and the mouse work fine too

* wacdump gives correct output, while X is not running, and wacdump
returns only 0 values while X is running

But
* The Gimp doesn't see any 'extended input devices'
* xidump -l doesn't see the wacom stuff at all
* xsetpointer -l doesn't see the wacom stuff.

I would very much appreciate any help,
Wijnand
