Hmm, a very interesting read for sure.

Just one thing: I'm not sure if VCCA is the real deal for todays Core2 Duo and Core2 Quad CPUs.
VCCA isn't even explicitly mentioned in the Core2 Quad datasheet. But, Vccpll is.

VCCPLL - Input - VCCPLL provides isolated power for internal processor FSB PLLs.
I'm not 100% sure, just one thing that I noticed today.
