This driver should be available. If it's not there, this suggests that
you did not set CONFIG_SENSORS_ADT7473=m when building your kernel. You
should have...

(Note: starting with kernel 2.6.33 you will have to use the adt7475
driver instead.)

We indeed do not support this chip yet. I've added your request to the
list on wiki/Devices.

I would trust sensors-detect. Maybe that Windows tool has decided that
the chips are compatible enough that the W83667HG-B can be handled as a
W83627DHG, at least for the feature subset it handles. Only a careful
inspection of the datasheets would tell. You may want to try loading
the w83627ehf driver with parameters force_id=0xa020 (to have the
driver treat your chip as a W83627DHG), force_id=0xb070 (to have the
driver treat your chip as a W83627DHG-P) or force_id=0xa510 (to have
the driver treat your chip as a W83667HG). Beware though that this is
untested by definition and we do not make any guarantee. It may
somewhat work for monitoring, but for example I wouldn't dare trying
fan speed control.

CPU core temperature support could certainly be added to the coretemp
driver. We are waiting for Intel to help. Huaxu, any progress?

The power draw value is news to me, maybe this is a new feature of the
Core i5 which could be added to the driver as well.
