From Ticket 1972, Gigabyte 7dpxdw+, making it work correctly

This is from Ticket #1972, Gigabyte 7dpxdw+, making it work correctly

Sorry, I should have been more precise.  This is a duallie board, so the
LM90 needs to support TWO external temperatures, instead of the usual one,
along with the usual on-the-chip sensor.  That is what is so special (or
odd) about this board.

Here's a sensor output of what I have so far:

From the w83627hf: the voltage readings are OK, the fan RPM readings are OK
as none of my fans have tach lines and the 3 temp. readings are a mystery.
They have nothing to do with the CPU temps.

Skipping down to the lm90, I assume the M/B Temp is the "on-the-chip"
sensor and the CPU temp is the one external temp reading that works.  If I
stall a CPU fan this reading will rise, so this one is good.  Of course,
it's way too high, but that's the way it shows in the BIOS and that's easy
enough to fix anyway.  

The problem is that the lm90 should have one more external temp for the 2nd
CPU.

The motherboard list of the above website shows the GA7 DPXDW+ with a
LM90-1 remote and a LM90-2 remote.  Alas, the program is closed source so
it's not much help.  The author also quit supporting this program so I
suppose emailing him and asking how he did it wouldn't be much help either.
