Wacom tablets, TabletPC and Xorg support for Ubuntu 9.04 (Jaunty)

Hi Loic,

The move away from xorg.conf has been to a new hal integration. Please see
the documentation in the wiki: https://wiki.ubuntu.com/X/Config/Input
Configuring  an fdi for your tablet hardware should not be any more
difficult than an xorg and could probably be accomplished by a script. I
believe that the move to hal support for input devices will make the
autoconfiguration much more robust in the long run and hopefully give
xserver the ability to "just work".
