I had an HP Omnibook may years ago that would overheat when ACPI was enabled. 
Apparently, HP leaves all thermal management to the OS when ACPI is used. As a 
workaround you could try to disable ACPI with "boot -2" (it looks like this 
works even though the boot mans page states that it is for i386 only).
