DSS on ZC7.5 cards

I have to implement the International Hydrographic Organisation S-63 1.1 digital signature scheme, which is based on FIPS 186-3 (the Digital Signature Standard) using the X9.31 RSA DSA.

The public key file under this signature scheme consists of the public key itself (y) and the domain parameters (p, q and g).

I can't see any way of extracting g from the RSA implementation on the ZC7.5 card.

Am I missing something?
