Well, neither of you answered the question. If HLT is never executed, then it won't save a lot of power, nor will it cool the computer. Your dump of ACPISTAT shows that HLT was never executed. Is that correct? Or is the counter not actually hooked up?
At least on my X60, the HLT version of ACPI does run cooler, and that's good, but without throttle control, any CPU intensive task will heat the machine to the point where it shuts off. By the way, IPIHLT is always zero on my x60, even though I know it runs cooler with the HLT version of ACPI.
