Digging further on, I came across
M1695 ... Tunnel Chip ... is ... chipset that uses a tunneling technique
to interconnect the two "North Bridges" as the South Bridge ...
Thus, the approach is as follows:
[ CPU ] <-- HyperTransport Link --> [ M1695 ] <-- HyperTransport Link
--> [ nForce3 250 ] <-- AGP Bus --> [ G550 ]
which implies that indeed we have two host bridges, but sequentially -
not in parallel.
