APM or APCI, if you are compiling 2.4.22 or above it has ACPI built in
and generally turned on by default, otherwise you have to patch it.

APM is in every kernel and for _MOST_ laptops should be off as they talk
ACPI better.  If you have both enabled, whichever the kernel tries to
load first wins ... hence the point of disabling APM.

What does dmesg say about all this? (right at the start of its output). 
You can also see if you have /proc/acpi or /proc/apm to further
investigate.
