Apologies, I should have said acpid.
To add further credibility to the dodgy software theory though, what hardware/firmware
protection mechanisms do you know of that upon detecting high CPU temperature dump the
user back to a login screen?
Returning to the login screen could be either a reboot or killing X, neither of which a
sane BIOS would do in a CPU overheat event. Every BIOS I've ever seen shuts the machine
down, which makes more sense if it's overheating.
