Indeed the G781 seems compatible with the other chips supported by the
lm90 driver, adding support to that driver sounds good. I'll gladly
review any patch.

GMT have a product sheet for the G7811 so it probably exists:
http://www.gmt.com.tw/product/datasheet/EDS-7811.pdf
Not enough to check for compatibility or write a proper driver though.
But its lack of remote sensor means it can't be fully compatible with
the ADM1032 anyway. Until we receive a formal support request and get a
datasheet (or at the very least a register dump) I think we can just
ignore the G7811.
