Further to the meeting discussion, here's more of my thoughts on lack of VT-d support.
Many of the myriad Intel CPU SKUs lack various misc features (without much rhyme or reason IMHO).
Many CPUs specifically lack VT-d support. Notably, in the i7 line, the "K" suffix CPUs lack VT-d.
See: http://ark.intel.com/products/52214/Intel-Core-i7-2600K-Processor-%288M-Cach...
look under "advanced technologies" and you'll see VT-d is "No".
I'd check once again on both your invoice and in the BIOS to see if your CPU # ends in a K and/or if your CPU # when looked up on Intel's site has "No" for VT-d.

Trever, you are dead on. The one I have is the 2600K. After our discussion I found http://ark.intel.com/MySearch.aspx?VTD=true which shows which ones are VT-d capable.
It's interesting that the recommended channel price for the i7-2600K is $317 while the i7-2600 with no suffix is $294 and has similiar specs but includes VT-d and TXT.

If you wanted a non-K instead, I could possibly hook you up and accept your 2600K as trade (you pay the difference). Of course there would be some loss of value as it is used and I'd have to find a buyer, etc.
I think the K's are more expensive because they have the newer/better on-chip video.
Again, I think Intel is going mental with their excessive SKU count with tiny confusing variations. One asks, what's the point? They're starting to look like a software company with SKU proliferation.

I can think of two possiblities for the proliferation. One is to recoup some profit on chips that have defective function (areas) on the die by selling them more cheaply than the original target. The other is to create confusion in the buyer so they have to depend on the <sarcasm> benevolent </sarcasm> advice of the vendor before deploying a desktop refresh company-wide.
IBM used the second technique in the 80s and switched their primary revenue stream from hardware sales to service sales.
