As was explained elsewhere in this thread (though I don't blame people
for missing it), the GPL mandates that additional restrictions may not
be applied to the code, and the CDDL contains restrictions (related to
patents) that the GPL does not. It's therefore not possible to
distribute something covered by both the GPL and the CDDL without
violating copyright law (unless one is the copyright holder).
Jörg Schilling, as I understand it, does not believe that the above
situation actually occurs, and that the CDDL-licenced and GPL-licenced
parts are entirely separate. Debian disagrees.
