Well, I never noticed this feature before. Am I correct in assuming it was installed with SP2 then? It does not appear it can be disabled either, I wonder what sort of issues this new feature could cause. Hmmmmm...
From what I can gather, it's not even that useful with out the stop bit. Can anyone remember the name of that hardware inbedded 'feature' Intel was developing, that would essentially give them control over your PC?

It won't work unless you have a processor that supports it. AMD designed it for their A64 processors and Intel bought it to slap in their Prescotts, so it's probably fair to assume that it exists in all successive AMD and Intel CPU's. I know that not much is expected of it from a technical standpoint, purely because it is in it's infacy and is targetting a very dynamic problem in malwares. Ever changing.
I wouldn't be too fazed about it being a privacy issue. I think you're referring to processor "cookies" - Pentium III processor serial numbers used for tracking activity or some crap like that. That was explicitly a privacy issue.

It was installed w/ SP2. Although the A64 was the first processor to implement DEP in hardware, SP2 will use software DEP for all processors unless you turn it off. You can disable it by editing your boot.ini file and changing the portion of the line that says: /noexecute=optin (or AlwayOn) to /noexecute=AlwaysOff. Some versions of the Forceware drivers (>61.xx through 67.xx) had issues with DEP when running some D3D apps. Nvidia has since fixed this issue.

EDIT: Yes, Excecution Prevention is only in WinXP SP2 and later
The 'feature' I am thinking of would actually be able to lock you out of your PC by way of control over the BIOS, I seem to remember it starting with the letter 'A'. It may have even been a colaboration between Intel and Microshaft.
AMD and Microsoft call it the 'NX Bit' (No eXecute). Intel call it the 'XD bit' (Execute Disable).
It's the same thing of course.
