Also
fetch www.fishercroft.plus.com/messages.gz
will get bits of /var/log/messages with the normal startup messages and
the output of

(sorry bad wrapping)
The two cpu temps come from coretemp.ko module.
While this was running I changed the temp with burnK7 and an icepack :).
It's clear that the messages do correspond to changes of state but there
are further triggers that I am not watching.
