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". -- Brooks
