Hmmm.... interesting.  Certainly possible, but the (Vista) driver would 
need to handshake with the card somehow to get the decryption key... 
unless it was hard-coded into Vista (would even MS be that stupid?).  
Thus it *should* be a matter of reverse-engineering a driver that could 
handshake with the card to get the key.

Much more difficult, perhaps, but maybe not impossible...

I prefer to remain hopeful :-)
