Since we are the linux kernel, we do have to care for legacy

Understood.  However, remember that SuperIO is a 1980's device that
predates the TPM.  Since the TPM requires special LPC bus cycles, it's
even less likely that an old chipset has an attached TPM.

Interesting - let me check with Georg tomorrow. Unfortunately I do
not have access to my tcg mails from home (since I'm not working :), 
but did you _explicitly_ talk about LPC and the system? I'm sure the
TPM does not care about the waitstates...

Yes, Infineon was one of the 3 TPM vendors who confirmed this.
