I'm not sure that I care what dmesg says, but I do want an accurate view
of our topology presented by the system, not some arbitrary and frankly
meaningless CPU count. If nothing else I care because the two cores
share one memory controller. That may not be all that noticable now for
normal application, but I expect it will be once we start seeing 4+ core
CPUs. Telling the user the (somewhat complicated) truth about their
hardware is part of "doing it right".
