I'll have a look at it.

However, if we're aiming for an SRU (even though I'm all for it) there's
Bug #292248: which suggest some Ubuntu/Debian patches might get in the
way.

Sadly, the LWP doesn't list the 0.8.1.4 (binary or source) drivers from
the Linux Wacom Project, else Matheus could have tried if they work for
him. Let's hope I'm wrong and an 0.8.1.6 Ubuntu packages fixes it.

If I'm completely wrong somebody might remember a bug in the LWP
that show they also encountered this bug in 0.8.1.4. But before doing
steps 2.1 and following, getting an Ubuntu package so
the users can test might help with 2.3

I'm planning to get up to speed with building packages for Jaunty, but
that will take me about a week (no kidding) of reading, and I can't code
(strangely, patching sometimes work on my end, but writting the patch
itself is out of my league). Jaunty still has 0.8.1.4, so I can't just
apt-get source, rebuild it for Intrepid and propose it to test to users
affected with the bug.

Last time i tried packaging xserver-xorg-input-wacom was for Feisty, and
after a few days I had to admit it's out of my league. I can apply a
patch that's done for a certain code, but the code between 2 versions of
the drivers change and patches from the last Ubuntu package aren't
straightforward on another version of the source code.

It's not I'm not confortable, it's just I don't know how to code and
I've tried that with xserver-xorg-input-wacom before, so I know it's not
an easy one (Timo Aaltonen has done great job for wacom drivers :hint: ).

However, if somebody can offer an 0.8.1.6 ubuntu package, or get one
into Jaunty, I can help other people try it and test it, and summarize
it for step 2.3

I'll get into it tomorrow. i'll create a page on the wiki, post some
mockups (for tonight I've spend too much time on launchpad already ;) )
and keep ubuntu-x in touch - ETA should be (at the maximum) before the
end of the week.
