2.6.12 uses 2.6.11 files.

The difference between beta (0.7.1-2) and stable (0.7.1) is beta X Wacom
driver grabs Wacom USB event so /dev/input/mice won't get them. That's why
you don't need to modify /dev/input/mice to /dev/input/mouse# if you are
running 0.7.1-2.

But this just works because the movement infos of the wacom

If this happens and you are running 0.7.1-2, there is something wrong.
Since you are running 2.6.14, it should not be a kernel driver issue.
Cintiq 21UX has been supported since kernel 2.6.12. However, to make sure
that your kernel DOES support Cintiq 21UX properly, please *more
/proc/bus/usb/devices* and *more /proc/bus/input/devices* (refer to
http://linuxwacom.sourceforge.net/index.php/howto/noctrl).

?

- In section 5.1  "Adding the InputDevices", what does the sentence

Tool type "stylus" defines the tip side of a pen;  "eraser" defines the
eraser side of a pen; "cursor" defines Wacom mouse (or Wacom puck in some
people's term).  Since LCD tablets don't have a puck, you don't need to
define it in your xorg.conf.

Email me your xorg.conf file to me directly.
