In this specific case, the problem is clearly due to nonsensical code in
the DSDT that alters the thermal trip points based on ioapic
configuration. It's only been observed on two almost identical models
from one manufacturer, and doesn't occur on any other known machines
with the same chipset. I think it's safe to special-case.
