That one (82801DB) is known for its hability to hide itself. Give a try
to the p4b_smbus driver (look in lm_sensors2/prog/hotplug), it might be
what you need.
If it works, you'll need to run sensors-detect again after loading the

The ADM1026 is your monitoring chip. It is I2C-only, so it has to be on
the supposedly hidden 82801 SMBus.

Get it from here:
chmod +x and give it a try :)

i2c-dev is needed to probe I2C busses. Since you don't have any detected
yet, it doesn't change anything. But it will if the p4b_smbus module
