If you like to sign with a smartcard, you usually have to use an external signature. Check the sample code I posted a few days ago for a possible way to combine this with timestamping. Copy the OCSP part from Paulo's example if you like to use OCSP as well.

However, this may not help you as you're interested in smartcards and that (usually) requires an external signature bypassing the iText code.
