Hello, with the current version of GPG 2 you can import 4096bit keys to a OpenPGP smartcard version 2.0. There is a bug in GPG2 that prevents it from decrypting data with a key longer than 3072bit on a OpenPGP smartcard. This should be fixed in the GIT repository. AFAIK a version 1 card doesn't support keys longer than 1024bit! "gpg --card-status" should tell you which version you have.
