Bugzilla Bug 133564

After installing 2.6.16-gentoo-r7 the mouse wheel on my Intuos 3 graphics
tablet was reversed. The previous kernel, 2.6.15-gentoo-r7, was fine. I was
able to fix this problem by replacing wacom.c in the kernel source
(/usr/src/linux/drivers/usb/input/wacom.c) with the one from the Linux Wacom
project -- 0.7.4-1.

Is this reproducible on the latest development kernel? currently 2.6.17-rc4

I just installed 2.6.17-rc4 and the wacom mouse scroll wheel works fine. 

Note that this is being tested on a 4x5 Intuos 3 mouse (cursor device in
xorg.conf) and can't confirm that it is affecting any other wacom tablet model.

Thanks, should be an easy fix.

Thanks for testing. Fixed in gentoo-sources-2.6.16-r8 (genpatches-2.6.16-10)
