I'm running a Dell M4400 with dual-core CPU and an older 8-CURRENT:
$ uname -a
FreeBSD current.Sisis.de 8.0-CURRENT FreeBSD 8.0-CURRENT #1: Thu May 28
14:40:45 CEST 2009     guru at current:/usr/obj/usr/src/sys/GENERIC  i386
$ sysctl -a | fgrep thermal
hw.acpi.thermal.min_runtime: 0
hw.acpi.thermal.polling_rate: 10
hw.acpi.thermal.user_override: 0
hw.acpi.thermal.tz0.temperature: 68,5C
hw.acpi.thermal.tz0.active: -1
hw.acpi.thermal.tz0.passive_cooling: 0
hw.acpi.thermal.tz0.thermal_flags: 0
hw.acpi.thermal.tz0._PSV: -1
hw.acpi.thermal.tz0._HOT: -1
hw.acpi.thermal.tz0._CRT: 107,0C
hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
hw.acpi.thermal.tz0._TC1: -1
hw.acpi.thermal.tz0._TC2: -1
hw.acpi.thermal.tz0._TSP: -1

the actual 68,5C is with KDE up, but nearly idle system; what does 
hw.acpi.thermal.tz0._CRT: 107,0C mean?

thx
