Ah, ADT7490. Please try:

http://dl.lm-sensors.org/lm-sensors/files/sensors-detect

We don't have support for that chip, but the datasheet suggests some
form of compatibility with the ADT7473 and ADT7475, which we do have
support for. So support for the ADT7490 is probably not too far away.

The presence of this monitoring ASIC explains why the hardware
monitoring features of the W83677HG super-I/O are disabled.
