That thread forked and re-forked a few times under the different
subjects...

Did you try setting

hw.acpi.thermal.user_override=1
hw.acpi.thermal.tz1._PSV=75C

in /etc/sysctl.conf?

If not, we can start by comparing machines and configurations. Mine is
X60 (1709-something) with 1.83GHz "Core Not-2 Duo" which is 32-bit
machine and I am running i386 version of -STABLE on it. I seem to recall
that there are 64-bit capable X60 models out there as well and someone
was running amd64 flavor on it. What's yours?

Are you using powerd? 

I do:
powerd_enable="YES"
powerd_flags="-a adaptive -b adaptive -i 75 -r 65"

What is the output of sysctl hw.acpi.thermal under light/idle load?

Mine is:

I might think of something else, but let's start with the stuff above.

I guess, I should mention that I have a habit of emptying about a half
of the can of compressed air into the grille on the left of the machine
every few months or so.
