ACPI is not only power management. It is all the information your
hardware conveys to your OS, about the setup and workings of your hardware.
Without ACPI, non-PM things like SMP, laptop dock/undock, and many other
gadgets fail to function (or are configured sub-optimally).
ACPI sets up interrupt routing, and Linux history is _loaded_ with
_years_ of problem reports that appear as timeouts, only to be resolved
as ACPI interrupt bugs (aka BIOS bugs, since ACPI tables come from BIOS).
