Does portion of 'devinfo -rv' similar to the snippet below show 'est'
attached to both CPUs?
<...>
    cpu0 pnpinfo _HID=none _UID=0 at handle=\_PR_.CPU0
        ACPI I/O ports:
            0x1014
            0x1015
      acpi_perf0
      acpi_throttle0
      coretemp0
==>      est0
      p4tcc0
      cpufreq0
    cpu1 pnpinfo _HID=none _UID=0 at handle=\_PR_.CPU1
        ACPI I/O ports:
            0x1014
            0x1015
      acpi_perf1
      acpi_throttle1
      coretemp1
==>      est1
      p4tcc1
      cpufreq1
