No problem.

OK, so it's a different board, which means that at least two boards have
the W83627EHF chip. And the driver would need to be written for 2.6
primarily.

You'd have to load some bus driver, most probably i2c-i801. The
"sensors-detect" script should tell.

Hexadecimal numbers ;) But maybe the address is different.
sensors-detect will tell too.

I've update the sensors-detect script so that it detects the W83627EHF
in the three possible ways: as an I2C client, as an ISA chip and as a
Super-I/O chip. Please give it a try:
http://www2.lm-sensors.nu/%7Elm78/cvs/lm_sensors2/prog/detect/sensors-detect

Download, chmod +x sensors-detect, ./sensors-detect, and send us the
full output.

David Madsen, please do too if possible! The more feedback, the better.

With the output of sensors-detect I'll tell you how to dump the chip
contents.

Thanks!
