I guess that's what the series really comes down to. The model is moving from (using 3-level PAE as an example): PGD => ...folding => PMD => PTE to ...folding => PUD => PMD => PTE Right? That's actually not the worst thing in the world, but it is a pretty big change. It moves the software model away from how the hardware works. It's a bit more grand than I thought from glancing at the cover letter.
