I recommend a visit to David Kanter’s Real World Technologies site. David recently published an excellent article on Intel Sandy Bridge architecture.
Intel Sandy Bridge Architecture
Pay close attention to the diagram on page 2. You’ll see this architecture includes an on-die (uncore) PCI controller.

David, sorry I wasn’t able to meet up with you at OOW 2010.
No problem, I’m sure we’ll meet up sooner or later – thanks again for the link.
David
Good read. Thought that was pretty informative.
