Well, you can file a kernel bug if you want, but it's a fair chunk of
new functionality and it's functionality that is very vendor specific
as it's not in the ACPI standards. For IBM thinkpads, see
http://www.thinkwiki.org/wiki/Tp_smapi

Be aware that tpm-smapi was refused entry to the upstream kernel, and
probably won't be accepted by the fedora kernel as a result. Consult
the kernel.org archives for the full discussion.
