What was the rationale? Can we get this one reverted? 

Some machines (HP omnibook xe3) have broken trip points -- too high --
so machine will overheat and trigger hw shutdown before starting
passive cooling.

That's really broken, and write to trip points is reasonable way to
'fix' that. (I'd understand if you only ever let trip points to
decrease... but otoh root should be able to shoot himself....)
