There's been a bit of bitching about the lack of info from vendors but no-one has picked up on Mark's comment, and talked about ACPI.
I've got an AMD notebook with PowerNow and ACPI support (in BIOS) and have exchanged email with someone who said that theirs (same model, but higher clock speed) was overheating UNTIL they enabled ACPI in the linux kernel. I'm just getting around to doing it myself but the direct implication is that ACPI allowed his linux laptop to run cooler... So, any comments on how ACPI helps? Can it exploit PowerNow or is it something else that makes it run cooler?
