Note: my model only has a digitizer (tablet PC model), no touchscreen (dual mode version)
Debian stable to the rescue
First I wanted to install Arch Linux on this system, but soon I encountered a severe setback : the Wacom stylus would not work. Then I tried Ubuntu 12.04 (Precise), everything worked out of the box, except the stylus!
Explanation : it seems the support for this older, serial Wacom tablet has been removed from the X.Org Wacom input drivers, since the 0.10.6 version and up.
(more info can be found here : http://ubuntuforums.org/showthread.php?t=1780154 )
Fortunately Debian Squeeze still uses a working 0.10.5 driver version!
