Thanks for the reminder and for the patch. I've just committed it to
HEAD and it should make it in to 10.0.

The readings in the original post look stable however, and very high.
It's possible the thermal control algorithm needs some tuning for G5
quad systems. Do you happen to know what the fans are doing? The quoted
CPU speed is also extremely suspicious here....
