As I understand, VanderPool is nothing else than a technology to let the CPU self-virtualize itself, something that's been around for decades on the big IBM systems, VM can run VM (or MVS or Linux)
Now why didn't AMD think of this when they designed the Opteron? If we may believe Chipzilla's timescales, it would have given AMD a two year headstart!
As for implementing it, I'm not an expert on these matters, but I don't think it would have cost a great deal of silicon, as they need to trap only a few extra instructions, a list was once published by Kevin Lawton on the plex86 site, and I've seen it somewhere else (X86-64.ORG?)
Actually, AMD seem to have discussed this when they desigened the Opteron, but guess who seemed to have stopped this? Yes, of course, the beancounters...
