Windows no, this laptop has run exactly 6 hours Vista while creating the
recovery DVDs, which I have no idea even where they are.

Hardy, Ibex have had no problems with this hardware, at least not
temperature/kernel related.

On Jaunty it's strongly varies on the kernel release. 2.6.27-1{1,4} work
somewhat, 2.6.28 does not even survive 60 seconds of burnK7.

See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/378065 for my
logs and experiences.
