I see. That's interesting. I have some reading to do on this wiki. :-)

That would be awesome. I checked the diff of the 3.5 kernel, and
grep-ed for intuos 5 code, there does not seem to be *that* much.
If ever you do it, a big big thank you!

I see. If the desktop is a 3.7, I guess the rt would be at least
3.5... hopefully.

Anyway if you were to upgrade Mga2 to 3.4 with backported Intuos 5,
that would already be the must-of. Intuos 5 has been out for like 6
month, and most people on most distribution probably think that there
is still no Linux support, whereas in fact it is already pretty well
supported!
I am playing with it since yesterday and that all works well until now.

Thanks for the answer and the information.
