like this

dmesg should contain stuff like this (dmesg | grep -i cpu)
CPU: Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz (1868.55-MHz 686-
class CPU)
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
cpu0: <ACPI CPU> on acpi0
est0: <Enhanced SpeedStep Frequency Control> on cpu0
p4tcc0: <CPU Frequency Thermal Control> on cpu0
cpu1: <ACPI CPU> on acpi0
est1: <Enhanced SpeedStep Frequency Control> on cpu1
p4tcc1: <CPU Frequency Thermal Control> on cpu1
SMP: AP CPU #1 Launched!
since I started monitoring yesterday, my cores are within 1 degree of
each other all the time, server running apache + samba + exim, mainly
as file and print server.
PS: I cannot find any man pages for est() and p4tcc()
The man page for acpi_thermal says it is part of 'device acpi' which
is loading, but is not finding anything thermal on this motherboard.
