Like these examples? (Block diagram on second page of each):

These at least split onboard I/O and PCI/PCI-e busses over two HT links,
each attached to one CPU of a four socket board.  Neat thing about these
boards is the two "external" HT links, to hookup a "daughterboard" (more
like kid-sisterboard, really :-) that is basically a copy of the main
motherboard, minus I/O -- four more CPU sockets, 16 more DIMM sockets.

Nice boards.  They max out at 8 sockets (16 cores with DC-8xx CPUs), and
128GB of RAM.

I'll grant you that I haven't seen a single or dual socket board with the
same sort of HT configuration, though.
