Now that I get what the value after the "Failed!" means, I understand
that I couldn't work anyway.

Please try replacing the value with 0xe9 instead. This will somewhat
force the detection, and sensors-detect will tell us a bit more (sort of
"if it was really a W83627THF, it would be in this state, at this
address"). If the details make sense, we'll continue.

If you did not do so yet, you can also try "isadump 0x295 0x296". Note
that this is potentially dangerous if it happens that this address is
used by something else (I think you can see in /etc/ioports to make sure
it's free).
