disclaimer - i'm still new to this [pgp/gpg] and not yet an expert, but
i've been doing a LOT of reading on it.... that said, i'll give your
question a shot....
do you want to generate a key that uses a single RSA key for both
encryption and signing?
$ gpg --expert --gen-key

Please select what kind of key you want:
(1) DSA and ElGamal (default)
(2) DSA (sign only)
(4) ElGamal (sign and encrypt)
(5) RSA (sign only)
(7) RSA (sign and encrypt)
and select 7... is that what you're trying to do?
of course, IIRC, PGP-2 specifies IDEA as the (only?) cipher, while openPGP
specifies that 3DES ~MUST~ be supported (among a choice of other ciphers).
there's a similar issue with SHA-1 v MD5. depending on exactly what you're
trying to do, you might have to generate a key-pair, then "key-edit" the
preferences to exclude SHA, 3DES, etc, not to mention that you'd have to
use gnupg-idea for IDEA support.
