i wouldn't count on it, but there might be a chance that you can read from
it using dd, copy it to a file, then try to recover data from that. worth
a shot, but in all likelihood, you're beat.

if that was feasible, pgp wouldn't be worth much.

yes.
other thoughts...
in theory, if you're *really* using a strong pass-phrase, you can publish
your private key in a public place and rest secure in the knowledge that
no known technology can break your 100+ character pass-phrase... and if a
hard drive or several go up in smoke you can recover a copy from google's
cache ;)
one thing i've thought about is using a one-time-pad to break a private
key into 2 (or more) shares. then send (using secure channels) each share
to one or more trusted persons who don't know each other. maybe put one of
the shares in a bank safe. if all of your hard drives explode on the same
day you can collect the shares and reconstruct your key.
