evdev: found only multitouch-axes.

Hello,

I've installed Debian 7.0 armhf to an Amlogic 8726-MX based android 
tablet. I use the original kernel from the android partition. I'e also 
installed xorg and xfce4.

It works fine with an external USB keyboard/mouse, but the touchscreen 
doesn't work with any of the X input drivers I've tried (evdev, 
multiouch, synaptics).

I've tried with the xserver-xorg-input-evdev 1.7 driver in Debian 7.0,
it didn't do anything. The experimental package is version 1.7.1, it
crashes as soon as I touch the screen. I've cloned the git version and
compiled it, it gives me the error message:

found only multitouch-axes. That shouldn't happen.

The tablet has a sitronix st15xx touchscreen, the driver is built-in 
to
the kernel. It generates MT events outside X if I watch it with 
input-events program.

I am aware of bug# 64029 which deals with this. So basicly this is a 
+1 message, that I am affected. I am willing to test or provide 
further information if needed.

The touchscreen is the main built-in input device on a tablet. The 
idea would be to use the touchscreen to move the pointer and generate 
click events, so that I can start and close programs, and use an 
on-screen keyboard to input text.

Thank you.

Bye
