I can report that 2048 bit RSA subkeys can be generated on the
machine, transferred to the version 2 card, and they work.
However, working with gnupg2 from Thursday VCS, 3072 bit keys
can be created, transferred to the card, and may encrypt files, but
decrypting the file failed with a cryptic "card error".
I am now happy with my 2048 bit keys :-)
