Hi Persmule,
I did some tests on thinkpad T430.
I disabled SeaBios CONFIG_TCGBIOS and was able to communicate with TPM
in GNU Linux, did a self test and took ownership.
It doesn't report as temporarily deactivated any more.

It looks like SeaBIOS' TPM driver is broken, possible related to this
fix:

Regards,
Patrick
