Yup just let mtwebster know what does and doesn't work, he doesn't have a tablet to use so he'll be relying on you folks to let him any bugs and exackly what does and doesn't work.
Version 19 of the driver says this for your tablet
Support for the new "Intuos" tablets (CTL-480, CTH-480, and CTH-680)
continues to be targeted for the eventual release of input-wacom 0.20.0.
version 20 says this
Its here! After an unexpectedly long wait for the patches to get
accepted upstream, input-wacom now offers backported support for the
three new "Intuos" tablets recently released by Wacom. If your new
tablet has been sitting idle for the past few weeks, now's your chance
to start using it
Grab a tarball and give it a whirl!
