Yeah, it's a feature come with EPT. Thanks for reminder! Would update the
patch soon.

PS: The latest spec available at
http://www.intel.com/products/processor/manuals/

It contains EPT and VPID and other new things on Nehalem. I would work on
clearing up the code according to the latest spec soon (yeah, we also only
got it for days...)
