This patch against linux-2.6.11-gentoo-r9 adds support for Wacom Volito2, Intuos3 and Cintiq graphic tablets to the kernel. You should consider adding it to gentoo-dev-sources. Please read these two threads. The patch is located at [1]: [1] http://bugs.gentoo.org/show_bug.cgi?id=95478 [2] http://forums.gentoo.org/viewtopic-p-2478951.html Note that this bug only partially depends on 95478, since the basic linuxwacom-0.6.8 package already provides functionality to Intuos3 and Cintiq.
I haven't got the slightest idea about what the evdev.c patch does; it was in the linuxwacom-0.6.8.tar.bz2 package (for the 2.6.11 kernel).
We tend not to accept feature patches. Please get this accepted into the upstream Linux development tree so that all distro's can benefit from this hardware support.
