Hardware attack on Trusted Platform Module

The big news of the last week in the Trusted Computing world has been an announcement of an attack on a TPM. The full article is very interesting to see how the attack took place.
The Trusted Computing Group has also published their opinion on the attack, which highlights that nothing is ever 100% secure, but more importantly the hack is just for one single chip – since every chip has a unique root key, finding it out on one chip doesn’t help you break another.
Furthermore, one question I have is what is the success rate of the attack? If the attack fails for a given chip and the attacker sets off the tamper detection, then the system the chip came from can no longer be hacked – if the hacker was trying to get a BitLocker key, for instance, a failure means the hard disk can no longer be read.
