I'd rather document the fact that the w83627ehf driver shouldn't be
loaded on this board. There's no point in slowing down the system boot
and libsensors by loading a useless driver. I've updated your
configuration file in the wiki accordingly.

Even better would be if sensors-detect would _not_ recommend loading
the w83627ehf driver on that board, of course. But for that, the board
manufacturer (or actually BIOS author) should disable the logical
device in question, which I presume SuperMicro didn't do.

No, it doesn't, nor should it. The w83627ehf driver, despite its name,
focuses on the hardware monitoring part of the supported chips. Other
features, including GPIO, would belong to a separate driver.

I have VTT monitored at 1.14 V on my Xeon E5520. On my Asus Z8NA-D5,
the limits are set by the BIOS to min = 0.770 V and max = 1.538 V. I
guess you could use the same limits on your board, this is very broad
but still better than no limits at all, and at least should be suitable
for all CPU models.
