Yes, I saw that in the archives.

However, Werner said in several mails that all that smartcard support that was 
in opensc is now also added to gnupg. He also said that all other cards are 
supported by custom code, so I wanted to know how I can use this non-OpenPGP 
card with openpgp.

Probably. However, I still need to sign mails with this smartcard, so is there 
still a way to use this card with the X.509 certificates with kmail / gnupg? 
For official documents I'll sooner or later need to sign with this card.
