Hi,

here is a patch that adds support for reporting the relative
(trackpoint) coordinates to the Elantech driver. Unfortunately, the Xorg
synaptics module simply ignores relative coordinates and evdev would
ignore absolute coordinates (as described above in #6) so there is
really no way, to have both device work with this patch (yet). But maybe
some more experienced developer will find my work on the Trackpoint
Protocol helpful and decides to write a good patch (I think the right
way to do it is to let the kernel module report relative and absolute
coordinates over two separate devices, which in fact is very hard to
achieve because the psmouse module is not structured for reporting to
multiple devices).

I have also included a Xorg configuration which enables Middle-Mouse-
Button scrolling and disables absolute coordinates (and therefore
enables the Trackpoint).
