The main decision factor for combining support for several chips in a
single driver or not is not how simple they are but how similar they
are to each other.

Here's my guess for voltages if it helps you:
in0: Vcore
in1: Vram (although a bit high, should be 1.8)
in2: +3.3V
in3: +5V with scaling factor 1.68
in4: +12V with scaling factor 4
in5: 3VSB or 5VSB with a scaling factor of 1.68
in6: unused
in7: unused
in8: Vbat

Please check your logs after loading the it87 driver, it might give
hints about in3 and in7.

If your BIOS displays voltage values, compare with those to validate
your lm-sensors configuration settings.

As for temperature, temp2 would be the CPU temperature, and temp1 would
be the motherboard temperature. temp3 is a bit too high to be realistic
so I'd be tempted to claim that it's not wired.

If you come up with a good configuration file for this motherboard,
please send it back and we'll put it on the website.
