Ok, this is what I have done and I have to say that it was not that simple for
someone that is not a developer ;)

So, I cloned the libinput repo :

$ git clone git://anongit.freedesktop.org/wayland/libinput

I modified the source (src/evdev-mt-touchpad.c) like this :

tp_init_hysteresis(struct tp_dispatch *tp)
{
        int res_x, res_y;

        tp->hysteresis_margin.x = 0;
        tp->hysteresis_margin.y = 0;

        if (tp->device->model_flags & EVDEV_MODEL_PRECISE_TOUCHPAD)
                return;

        res_x = tp->device->abs.absinfo_x->resolution;
        res_y = tp->device->abs.absinfo_y->resolution;
        tp->hysteresis_margin.x = 8;
        tp->hysteresis_margin.y = 8;

        return;
}

I rebuild it  :

$ cd libinput
$ ./autogen.sh --prefix=$WLD --enable-event-gui

I didn't found the needed dependencies so I installed them each time it
complain :D 
By the way it's not so easy to find that "--enable-event-gui" is needed to
build the event-gui tool.

$ make && sudo make install
$ sudo reboot

It seem that worked because with the 2.1 firmware it's much much better, there
is almost no movement, like with synaptics. With the 2.0 firmware there is no
visible change since it already worked pretty well.

However I don't know how to use the event-gui tool.
