This is really helpful. I think it would be great if there were some way to
color or designate devices per chip. I was looking at
http://www.coresystems.de/~stepan/devicetree/dot/static-tyan_s2892.png and I
couldn't see the second Opteron. Am I missing something? If each chip were
colored or enclosed in a box it seems like it would make it easier.
http://www.coresystems.de/~stepan/devicetree/dot/static-tyan_s2895.png I see
the second Opteron's northbridge_amd_amdk8 and it's related 6 pci functions,
but I don't see two cpu_amd_socket940 apic or chip constructs.
