Yes, but as you can see they are not nested under coretemp. devices:

    cpu0 pnpinfo _HID=none _UID=0 at handle=\_PR_.CPU0
        ACPI I/O ports:
            0x414
            0x415
      acpi_perf0
      est0
      p4tcc0
      cpufreq0
    cpu1 pnpinfo _HID=none _UID=0 at handle=\_PR_.CPU1
        ACPI I/O ports:
            0x414
            0x415
      acpi_perf1
      est1
      p4tcc1
      cpufreq1

This seems to be at odds with the dmesg and sysctl view of things?

Cheers,
