Guys,
Thanks for the replies, but it's clear you do not know the answer(s) either! 
I'm not saying there's a conspiracy theory here, but there's more to it than this.
Whether or not a chipset revision officially supports AMT/ME, they are bothering to not only include it in their system BIOS and future revisions, but provide updated ME software for those exact systems that supposedly do not have any ME enabled?
No one, not Asus, not MSI, not anyone ever... would bother to do this for no reason. It involves work, and by definition, work sucks. No one would bother interfacing to this code, especially having end users flashing BIOS chips thereby risking failed flashes and RMAs that ultimately the vendor has to pay for... no. I don't believe that for a second. So what's going on? Why do they implement it, when in fact they don't implement it? It makes no sense.
Hmm. Thinking aloud here. What if... it's partial? Maybe 3rd party or certain tools still work? Since I see $METDT references and a large block of binary code associated with TDT (Theft Deterrence Technology aka AT-p) in the ME BIOS region, so perhaps something like Computrace could access that select bit of ME?
Gates help me. I am going to go a bit OCD on this. I will find out. I need to.
Thanks in advance for any assistance to the cause!
