I have the same problem as was answered by David Shaw in 2004: http://osdir.com/ml/gnu.gnupg.users/2004-06/msg00022.html (Converting a veeeery old PGP key (2.6.3ia) to GnuPG.)
However the method he suggested does not work for me: $ gpg --s2k-cipher-algo cast5 --edit-key 0x5D144299 gpg (GnuPG) 1.4.6; Copyright (C) 2006 Free Software Foundation, Inc.
