See reply to Laurent regarding thermistors.

And yes, I did report the running temperature as 143 degrees F. I should
have specified that the reported temperature was read when the laptop was
sitting on a coffee table working correctly. What I need is some
temperature readings at the point where the system stops functioning.

That is great advice. The problem here is that the fan is not coming
on and performing its function. That function being, to move air
through the machine and cooling the system down.

I wouldn't have bothered posting anything if the fan was coming on,
and blowing hot air out the side of the laptop. If the machine
locked up, fan running and everything hot as hell, I would have 
concluded that it was overheating. But in this case, the fan is not
coming on. Since it's supposed to, I've decided to ask questions.

Sadly, since there aren't any temperature reporting programs
for OS X, I doubt the kernel has support for telling the cooling fan
to come on either. Since the machine is so old, I doubt support for
the fan controller will be built into any future releases/updates.

Great point to know regarding when the fan turns on in your system.

So, it appears that I should attempt running OS 9 on the system for
a while and see what happens with the temperature and fan during 
use in the same situations as in OS X. If the reason the fan is not
coming on because the kernel lacks support for it, then OS 9 should
solve the problem. 

I first have to decide if this is the route I want to go. I'm quite
enjoying my OS X experience and much prefer a ssh(1) over MacSSH.
