The problem with the coordinate transform matrix not working is solved by this patch: http://patchwork.freedesktop.org/patch/12471/

These touchscreens sometimes only send one axis if the other axis hasn't changed. The server would take the new untransformed X axis sent by the screen and the saved, *post-transform*, value of the Y axis, and then apply the transform to that. The patch fixes it to take the new X axis and a saved pre-tranform Y axis and transform that.

I can also confirm that emulate third button appears to be totally non-functional with an atmel touchscreen.
