It is rather backward, IMHO. I did implement a passive cooling
feature as an enhancement of powerd(8) like you did, during initial
phases. Then, I implemented it in our kernel as a result.

I'll take a look at your patch. Umemoto-san is right in that you really
want the kernel to control cooling. What happens if powerd dies/hangs
and your system burns up? Passive cooling is often a last resort to
keep the system from overheating.
