    How about comparing /sys/devices/system/cpu/cpu0/topology/core_id and
    /sys/devices/system/cpu/cpu1/topology/core_id values?

    On my northwood ht (single core) cpu0/topology/core_id and
    cpu1/topology/core_id contain "0". For dual core system should be
    something like

    cpu0/topology/core_id = 0
    cpu1/topology/core_id = 0
    cpu2/topology/core_id = 1
    cpu3/topology/core_id = 1

    Regards,
    Michal
