I'm not sure what OpenPGP cards have to do with this, since I'm talking about
PKCS #11.  I can use a PKCS #11 device with X.509, with S/MIME, with TLS, with
SSH, with IKE, and quite probably with a number of other, lesser-known
Internet security protocols.  The one significant one I can't use it with is
PGP.

Yes, see above.

You still can't use it with PKCS #11.
