3-key-EDE-DES in CBC mode should work.  If you need plain old DES I
will implement it.


DES/SK is not implemented because it is marked as an reserved
algorithm in OpenPGP and not further specified.

No, the encryption algorithm should just do an ECB and we build on
that in cipher/cipher.c to implement CFB and CBC using a generic
method.  This is not the fastest way of doing so but saves us a lot of
work and code.
