Yes, that is now set and it keeps the machine from overheating BUT
the machine bounces around alot when doing any real work, like a build.
So the heat gets up to 80 then the CPU goes down to 125, then the heat  
comes
down etc.

I am running i386 as well and I think our machines are identical.  I  
have been
avoiding bringing it into the office (so I get $realwork done) but may  
bring it in
this week to tinker while builds run.

I have tried powerd but, at least emprically, it seemed to cause
the bouncing heat/CPU speed issue to be worse, that is, higher peaks  
and troughs.

It NEVER gets down to 40 except when I turn it on.  At idle the tz0  
and tz1 are
60 and 62 respectively.

Mine is again hotter, 60 or so on the first thermal.

That I am not doing as yet.

I think I have one higher level, 2000/something at the start.  I'll  
look tonight
or tomorrow.

Sounds good, I'll get real output tonight/tomorrow.

I have read things like this on the net as well.  I can try that when  
I bring the box in
to work as well.
