BugLink: http://bugs.launchpad.net/bugs/606278 The first driver backported is the Wacom tablet driver in order to support newer models. This backport took the wacom driver version 0.8.8-8 from http://linuxwacom.sourceforge.net/. Backporting the kernel driver from more recent kernels is rather complicated as those depend on additional changes in the input core driver (multitouch slots).
