This is what you could do to check your info.

$ sysctl -a |grep thermal
hw.acpi.thermal.min_runtime: 0
hw.acpi.thermal.polling_rate: 10
hw.acpi.thermal.tz0.temperature: 2950
hw.acpi.thermal.tz0.active: -1
hw.acpi.thermal.tz0.thermal_flags: 0
hw.acpi.thermal.tz0._PSV: 3732
hw.acpi.thermal.tz0._HOT: -1
hw.acpi.thermal.tz0._CRT: 3732
hw.acpi.thermal.tz0._ACx: 3732 -1 -1 -1 -1 -1 -1 -1 -1 -1

If there is no thermal you may not have support for it.  I read on the 
list where centrino now has full powernow(or something) support on BSD.  
Also search the acpi list for your board and/or bios.  There are some 
black listed products because acpi is broke on them.  I seem to remember 
some asus products mentioned.  Read the handbook about fixing or forcing 
acpi to load too if it is note black listed. 

Acpi is on in the bios and being loaded as a module right?
