Do you want to use a card reader with or without PIN pad? In the first
case, I recommend the SPR532 from ACM (also called pinpad pro). If you
prefer a small one, try the SCM SCR 335.

The Fellowship card supports up to 2048 bit keys (for signing keys even
up to 3072 bit keys) because it is an OpenPGP v2.0 card. AFAIK, there
are currently no cards that support 4096 bit RSA keys in the market at
the moment (I might of course be wrong about that).
All the best,
