Does x86 uses TPM 1.2?
Yes, it is at least available there, how much it is used is a different
question.
Seems like something that it's in the code because QEMU supports it,
but in the end people uses 2.0 all the time. However, I can't backup this
claim and I have no desirable of making x86 people angry, so let's leave
it at that.
