These cards are not anymore distributes for some years now. The current
card (Fellowship card or those from kernelconcepts) support 4096 bit
RSA. However, they are advertised with a limit of 3072, because only
recent versions of GnuPG can cope with more than 3072 bits.
However, I don't see any reason why one should use more than 2048 bit
with the card. Are you sure the OS and code of the card is secure and
reliable enough to hold up with the security expectations of a larger
key? I am not.
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
