That's very generous!  I may contact you later if I have a need.
I was really just half-joking...

Ah, have you tried memtest86?  http://www.memtest86.com/
Let it run for a week if you have the time - seriously.

Just for the record, what mainboard is it?

I assume the BIOS shows two CPU temps and a system temp, right?

I assume these match the BIOS and you're satisfied with them, right?

BTW: You emailed the rest directly to me, but I've been traveling.
Please continue to reply to the mailing list... you could get
the experience of more people that way (and leave a trail for
others to follow).

If the w83781d is already loaded, it will prevent the w83627hf from
attaching to the sensor chip.  See if it works when you *only* load
the latter.

How do these match up with your BIOS readings?  The easiest way to
determine which are CPU temps is to run something CPU intensive for 
several minutes and watch for the temps to jump.  A kernel compile
(with 'make -j4' for your dual Xeons) should do this for you.

The system temp may rise as well, but not as much and more slowly.

I think you're pretty close, really.  Just try the couple things I
mentioned and let us know how it works out.
