If you have a macppc box with a G3 (G3 only; the temperature sensors
don't exist on earlier processors and exist but are documented to not
work on the G4), the 'envstat' command will report the CPU's internal
temperature.

I know that the iBook, at least, has a couple of motherboard thermal
sensors as well, and I've tried to read those but haven't succeeded
yet (the i2c interface to them is kind of annoying).
