Ultrix reports power supply overheating like as;

$ strings --print-file-name kn*.o | egrep eating
kn02.o: System Overheating - suggest immediate shutdown and power-off
kn02ba.o: System Overheating - suggest immediate shutdown and power-off
kn03.o: System Overheating - suggest immediate shutdown and  power-off

NetBSD/pmax trys to detect power supply overheat condition.  I'm not
sure the code works in practice, though.
