Well, I have an option to set the CPU in the bios to high, low or auto to extend battery life.
If I set it to high performance it will double fault almost immediately at boot.
Set at low performance it double faults just after ACPI chips in. It mentions setting the thermal zone and then halts 6 out of 10.
The 2.4 kernel (slackware11) hasn't faulted yet so next step'll be enabling acpi as like your XP, it gets awful hot.

I almost have the impression it doesn't, any more. All the heat certainly doesn't extend it's life span.

This is my teenage daughters laptop. Doesn't do that much, though I have noticed that "amsn" (and kopete) when in use rocket cpu usage up to 90% or more. That's when the thing really gets hot, including the wireless pcmcia card.
