Well, it is a bit moot as far as I can see because the only hit for a
card I saw in the first couple pages of a google search was one that
cost around US$700 (there were a few other hits but the cards are no
longer available...)

Getting good quality RNG sources is always a challenge... if you are on
a modern x86 platform then the TPM chip can provide them.  The TPM is
also capable of enctyption but it is not intended for bulk encryption,
the interface is too slow/limited for that.
