The thermal control is (supposed to be) handled by the operating system automatically. The power states are in the ACPI spec. This stuff is still under development so some features may not be fully implemented. :) since the systems config still includes apm controls, I am assuming that we keep both, but people need to be warned|told which are 'safe' and what happens if you enable apm and acpi simultaneously. Actually, when you go into ACPI mode, APM is disabled.
