Stefan Bader - Dec. 2, 2010, 1:21 p.m.
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).
