You should (I think), in principle, be able to distinguish them using
the GdkInputSource (GDK_SOURCE_MOUSE vs GDK_SOURCE_PEN). If the
tablet isn't giving events as GDK_SOURCE_PEN, look at the gdk source
code and see how gdk determines this information from the XEvent,
and make sure your driver is giving the proper information to X.

me if I'm wrong.
