I just know what he did. His clutch did nothing, but this is getting
fairly off topic. He was able to gun the engine a little, and slide
it into second at stop lights, then lug the engine through it. It was
the strangest thing that I ever saw...

I have a machine that does this. My Dell Inspiron 8000. The reason
that it does this is because the disk spinning down has nothing to do
with APM. The BIOS tells the disk to spin down when it has been idle
for 30s. When FreeBSD boots, it doesn't give orders to the contrary,
so it still spins down when it has been idle for 30s, regardless of
FreeBSD's APM or ACPI use.
I've commented on how I think that it should be in other mail.
