Hi Ping and Chris,

(Ping is the Wacom developer who helps maintain kernel and X drivers.
Chris also does quite a bit of Wacom development.)

Can you comment on the request to apply these patches to Ubuntu 12.04
LTS? Do you recommend we add these, keeping in mind that this is a
released stable product, and we need to guard against potential regressions?
