...depending from what kind of sensor and managability hardware you run you 
might able to use i.e. temperatures or fan speeds up to hardware failure states 
(from IPMI or BMC subsystems) to give you a chance to proactively drill your 
machine down if it makes any sense to you. Not shure how far many sensor types 
are supported with drivers but i assume the most spreaden should be working 
under NetBSD.

Depending from your machines ACPI implementation it should kick your OS down 
when it means it is better to halt byself because of broken sensor parameter 
windows....


cheers,


Niels.
