This is certainly true.  However, if somebody compromises your system
with the smart encryption card, then they can probably use the card to
sign things.  This isn't as good as having your key, since if you can
close the hole you don't necessarily have to repudiate the key
(although you probably should).  There's no perfect solution, of
course.  All of the solutions we've talked about make sense given
different cost/benefit scenarios.
