I 'ported' the Linux Dell SMM driver:
It exports some sysctl's exposing the fan status and the CPU temperature.
Note the quotes -- it's still pretty experimental, and covered under the
GPL instead of BSDL.
The rest of the temperature readings are in hw.acpi.tz IIRC, but my
laptop is not turned on right now.
Remember, kids: "Q" is always followed by "U". You can learn more on the
