1. The card generates a 2048 bit RSA keypair, but when trying, for  
   example, to encrypt data with the public key the card seems to throw  
   and SW_UNSUPPORTED_FEATURE exception - this problem doesn't happen  
   with 1024 bit keys.

With NXP JCOP cards I have the following experience: even if it
is printed on the backside that they support RSA up to 2048 bits,
their largest key size is 1952. For bigger key sizes either
RSAPublicKey.setModulus throws CryptoException.ILLEGAL_VALUE or
RSAPublicKey.setExponent throws CryptoException.ILLEGAL_VALUE.

I would try slightly smaller keys.

   2. The random number generator doesn't seem to work... (even though  
   the card supports it).
   
No idea here.

Bye,

Hendrik
