ACPI is also used for things like power management & battery monitoring
(for instance, on laptops).
The implementation of ACPI varies by manufacturer & bios. A lot of the
"linux on laptop" pages will have specific details about what features
work, and what doesn't work.
AFAIK, APIC is mostly used for multi-processor systems.
