Yes, I would agree that a repeated message is much more of an annoyance
than having it just happen once at boot time. With a Pentium D, there
probably isn't a core temperature monitor at all (I *think* that's true
for all of them, but it's definitely true for some), so you just want to
turn the messages off.
Unfortunately, I can't browse sources now, but I think that what happens
might be controlled by events going through devd. If that's correct, you
should be able to add an event rule to drop events related to your
non-existant thermistor (or delete one that already exists). You also
might be able to change the polling period for the thermal device.
