Great!
the 3177 mod clearly works, we will add support in CVS.
You are unlikely to have a LM80 (often misdetected) or a w83781d
(i2cdetect doesn't look right).
Look at your board or ask your board maker to identify sensors chip.
You can also send us the output of i2cdump 1 0x1b and i2cdump 1 0x2f
and we can try to identify the chips at those addresses.
