Good news! I was able to make my 2 wacom devices (touchscreen and
Intuos2) work correctly in Krita using the attached patch against Qt.
Chase Douglas was right about Qt incorrectly using the recieved events
because not all axis are sent. I simply updated Jussi's patches like
that:
Instead of just
I had a look at the Krita sources, as pointed out by Jussi, and the
problem does not come from the kis_canvas_controller code, but seems to
come from kis_canvas_widget_base.cpp.
There, we have the following code:
void KisCanvasWidgetBase::processTabletEvent(QTabletEvent *e)
{
Animitim, the uTouch Qt4 package is still building (at least from what I can
see), it is the following version:
qt4-x11 - 4:4.7.4-0ubuntu3~utouch1
So I think you don't have the update yet. Will try tonight myself.

As suggested by Jussi, I tried the tablet sample app from qt4-demos, and

If I remove all the latest patches starting from the 503, it works fine
(pressure ok and no jumping lines).
I see no difference if I only apply the struct changes described by Jussi in
comment #32. Pressure and everything still works
Pressure works for me on my own recordings. Maybe you need some
calibration or configuration of the Krita brush. I can see a very small
sign of pressure sensitivity on your recording : the beginning of the
first stroke is slightly grey , meaning the opacity was not at 100%

I investigated a bit and reverting the fix for issue #774938 (1) fixes the
problem and my touch / stylus work correctly.
So the regression is introduced by the following patch
