I'm wrapping up preparation for another release. The driver refactoring and simplification is done, and as the last change I just merged the addition of X.org configuration for the tablets which are supported by the Wacom driver. Now you wouldn't need to enable the Wacom driver for them yourself (your existing X.org configuration in /etc will take precedence, though).
See the updated README.md, please try the new version and report any issues, because next weekend I'm going to release v9!
After that I'll finally take onto contributing all the latest drivers upstream, without distraction.
