I have an old backup machine that doesn't reboot or powerdown in Linux, but yesterday I got the idea to try apm=off at bootup. The machine now reboots and powers down perfectly.
I'd like to know why, but the only anomaly I noticed is that
APM is disabled in the BIOS. If APM is disabled in the bios, does that mean you _must_ turn it off in Linux also to allow reboots and powerdowns to work? Or is that just a coincidence
on my machine?

in theory it's coincidence, because ACPI's presence is supposed to force unload of the APM modules. However, something about your laptop could be making the APM stuff hang up?
I've noticed the same on other systems (non-laptops). That is apm was running, they wouldn't shut down. But turning that off would fix the problem.
