There's never no possible backdoor, but yes I think in order to effectively do this and not involve my whole company like the article described you may have to have to involve Intel (and AMD is coming back, so them too) to go all "trusting trust" on this problem. And even then people may notice that their FDO profiles seem to be broken, and other "huh, that's funny". Also other shops that actually obey SOX, and actually care about two-key systems (or multi-key) will not be able to keep this a secret. The same protections that work for SOX and "sysadmins kid was kidnapped and they demand a backdoor be inserted" will work for this. Sure, companies that protect against none of these will fail. But if you actually have systems in place to protect against "rogue employee" then this kind of order requires breaking ALL of these systems. I expect most companies to have no such systems, but the important ones do.
