No, this didn't have any effect on the coolers. If I set
hw.p4tcc.cpuperf_performance to 13 (the lowest available)
hw.p4tcc.cpuperf follows. But I can't see wether it's slowing down the
processor, and it certainly don't slow down the coolers :(

I tried APM too, but it simply didn't work. I can't even get battery
info from it. I didn't work much on it other than enabling it through
rc.conf and loader.conf. I tried apm -e 1, but that didn't have any
effect either.
