coretemp *does* seem to be built into the GENERIC kernel, or at least
that's what it told me when I attempted a kldload. I had also earlier
looked at the temperatures with a similar command. This is stable/10,
by the way.

For what it's worth, CPU temperatures seem to be entirely reasonable.
When I was running memtest86+, it reported temperatures around 40-45
C. The sysctl command now returns:

hw.acpi.thermal.tz0.temperature: 27.8C
hw.acpi.thermal.tz1.temperature: 29.8C
dev.cpu.0.temperature: 40.0C
dev.cpu.1.temperature: 40.0C
dev.cpu.2.temperature: 40.0C
dev.cpu.3.temperature: 40.0C

Appreciated. I have added this to the loader.conf on my notebook.

This will be the next step (I'm still restoring the ports tree).
Thanks!

I'm short a mouse at the moment, so I can't use X, but as I sort my
way through this, that can happen later.

Thanks!
