You don't want DSA on smartcards - at least not until they are able to
do deterministic DSA (rfc-6979).

Perhaps this is more a discussion for gnupg-devel or even not a gnupg
mailing list at all?
I have a question regarding the current OpenPGP Card for Werner: does it
blind RSA calculations? If not, is there a different firewall against
using power analysis to obtain the secret key?

Then publish it anonymously. Most TV card hack software is also published

Ah-ha! Amtel are apparently offering samples of their
AT91SC512384RCT[1], which has an impressive set of features including a
cryptographic accelerator.

Only if that card may be used to create clones of TV cards.

OpenPGP is define by RFC2440 and as "open" as any RFC. The OpenPGP
card Speification by Achim Pietig and me is very similar to an RFC.

You want a chip with a hardware accelerator for RSA. RNG's are not the
problem.
