Well, apart from the code from Intel we also have had VT SDVs in Cambridge for
quite some time and so are able to test stuff for ourselves. I'm not sure
what the status is for AMD: but there's always SimNow for development /
testing. So in both cases there's some sort of reference implementation to
work with.

My initial impression of Pacifica was "much like VT, but with more
goodies" ;-)
