        According to that page, it supports 3072 bit keys (which I
 understand is perhaps overkill).

        I just bought one :-)

        I have a 4096 bit RSA key -- can I create 2048 or 3072 bit
 subkeys and only copy these keys to the card? Or will the fact that the
 primary key is 4096 bits stymie the operation?
