(8) For TSO-C129/129A users, any required alternate airport must still
have
an approved instrument approach procedure other than GPS that is
anticipated
to be operational and available at the estimated time of arrival, and
which
the aircraft is equipped to fly. If the non-GPS approaches on which
the
pilot must rely require DME or ADF, the aircraft must be equipped with
DME
or ADF avionics as appropriate.

I believe the last statement means what it says - that for purposes of
selecting a valid alternate, one must select an approach that can be
completed without reliance on GPS.

"What it says" depends on how one interprets "as appropriate".

(a) Since it is "appropriate" to substitute GPS for DME and ADF on
non-GPS approaches, then it's acceptable as far as I am concerned.
Furthermore, (b) The aircraft is "equipped to fly" the non-GPS
approach.and (c) they'll never catch me anyway even if I'm wrong.
