Hmm... come to think of it, the CPU is also quite hot (95°C), and it usually
shares the heatsink system with the GPU/north bridge, so the problem might
be on the CPU side of things.

While it can easily be a hardware problem in the heatsink, we could also
have a screwed up ACPI thermal control in our hands once again (either
kernel bug, or bogus ACPI firmware in the laptop).
