Hi,
IMHO the best solution would be to upgrade opencryptoki, including
Wheezy. Trying to backport many patches will be complex to maintain and
will create a version that could be very different from upstream,
leading to bugs (on functionalities, and security).
tpm-tools can be compiled without opencryptoki, but this would disable
the pkcs#11 support and so loose some functionalities. Except the
dependency in debian/control, there should not be any other changes to
be done.
Cheers,
Pierre
