Are you familiar with this:
http://code.google.com/p/opencryptotoken/
It does ecc and as it is based on an atmel micro controller, adding a display
is pretty straight forward

We have been accepted as a mentor organization for Google
Summer of Code (GSOC) 2013. One of our project ideas is to develop a
physical BitCoin wallet according to
https://en.bitcoin.it/wiki/Smart_card_wallet
A word of caution: hardware Bitcoin wallets really do need some type of
display so the wallet itself can tell you where the coins it is signing
are being sent, and that in turn implies support for the upcoming
payment protocol so the wallet can also verify that the address is
actually the address of the recipient the user is intending to send
funds too. The current Crypto Stick hardware doesn't even have a button
for user interaction. (press n times to approve an n-BTC spend)
Having said that PGP smart cards and USB keys already have that problem,
but the consequences of signing the wrong document are usually less than
the consequences of sending some or even all of the users funds to a
thief. You can usually revoke a bad signature after the fact with a
follow-up message.
Not to say hardware security for private keys isn't a bad thing, but the
protections are a lot more limited than users typically realize.
I will say though I am excited that this implies that the Crypto Stick
could have ECC key support in the future.
