AFAIK all the magic is done by acpid. It checks the ACPI event
interface in /proc (IIRC /proc/acpi/event) and according to that event
it calls the specified script (see /etc/acpi/events) with a couple of
cmd line parameters.

I can't help you with you with the thermal, battery, etc features
'cause I've only used it to make the power button do a shutdown on a
couple of desktops.

BTW: you can "disable" the power button on an ATX case by loading the
button ACPI module and not running acpid (or set it up to ignore it) :)
