You might ask on the pgp-users list as well.  A number of people there
work at pgp.com, and/or have access to the PGP sdk source code
(something which I'm reluctant to look at for obvious reasons).

Note, by the way, that while the sdk datasheet does claim SHA-512 as a
supported hash, the PGP 8 datasheet does not.
