One of the key questions underlying all of this has been the question
of *which* GDM, if there are multiple, should get the event from
*which* reader.  If you bind together the biometric reader with the
existing keyboard/mouse/ display group, then it's easy to see how this
works.  If the fingerprint reader is dangling in space, it's less
obvious how it works.
