Interesting. So to grab a CPU is needing this condition - available and correct 
Private Key.

"The key is generated during power-up by the BIOS, and should never leave the 
controller."

What if there is a flaky memory or something? Say you generate the key and 
store it somewhere, but a bit is written as 1 instead of 0 or vice-versa. What 
do you do then? What checksum and fixing are there to fix it on the fly?

Will that new trick stop that Meltdown/Spectre vulnerability?
