The BIOS bug in these machines is that they set the thermal trip points
to 16 degrees C if the APIC is set up in a specific way. It's specific
to the HPs and it was there in the initial BIOS release - before anyone
added workarounds for the SB700 issue. It's clearly and unambiguously
broken, and it's clearly the BIOS's fault. However, it's also clearly
our responsibility to avoid triggering it on this hardware.
