About a week ago, an XServe G5 of mine started powering off more or less 
randomly (after 1 hour, chances were good it for it to occur). A 
problematic UPS has already been cut from the loop, and today I cleaned 
the machine inside out with pressurized air. So far it runs, for now at 
least, with a load >= 2.0, but I am keeping an eye on whether this is a 
thermal issue.

To that end, I wanted to obtain some statistics. Despite 
sensors-detect(8) loads lm87.ko for me, running sensors(1) shows no 
sensors. Oddly enough, I found a "kfand" process running that seems to 
stem from therm_pm72.ko, which brings me to the sysfs files.

Is there a reason sensors(1) is not supported for Rackmac3,1?

Certain sysfs files have a value with an unknown unit.
"current" is likely in Ampere, temperature must be in Celsius
(because there's no way the server room is 54°F=12°C cold).

Is there a way to obtain the trip points for the hardware?
