This is great news but it did not work on my setup:
os767 with a BambooFun tablet.

I do not see any entries for the wacom in /dev/input
and a wacdump of all the possible /dev/input/event#
entries showed all unknown.

For my yum install it pulled the same version as Gary
reported.

   Had you done some previous installs that might have
   done addition configuration or driver installs?

   What version linuxwacom do you have?

   What /dev/input entries?]

   What do you see with wacdump for them?

Also, the sudo cp of the xorg-dcon.conf from the Colors!
instructions does not have the '!' in it and will not
work.  I had do su to run the command and escape the
'!' as a history expansion character with a backslash.
I was not able to get a combination of escapes that
would work with the sudo emulation...
