Want to report that the wacom.ko from Paul was also the final step in
bringing my Wacom Intuos to life. Is there some magic trick to getting
it to the insmod wacom.ko after a reboot (I have to run it again after
each boot)? I'm sure this is standard kernel hacker fodder, but not
something I dabble with much.
Great to see this working!! How's best to get this into the 9.1
distro? Does this need a ticket to get formal attention?
