Hi

I have an Intel DP55WB motherboard which sensors-detect reports has an 
adt 7490 chip.

Probing for `Analog Devices ADT7490'...                     Success!
     (confidence 5, driver `to-be-written')

I downloaded the standalone driver from:
http://khali.linux-fr.org/devel/misc/adt7490/
as linked from:
http://www.lm-sensors.org/wiki/Devices

After building and modprobing, sensors reports:

                       (crit = +100.0°C, hyst = +100.0°C)
temp2:       +35.2°C  (low  = -127.0°C, high = +127.0°C)
                       (crit = +65.0°C, hyst = +61.0°C)
temp3:       +37.8°C  (low  = -127.0°C, high = +127.0°C)
                       (crit = +65.0°C, hyst = +61.0°C)

The fan speeds look plausible, compared with what I have seen reported 
in the bios.

But, I was expecting to see temperatures for each of the 4 cores in the 
i7-860 cpu.

I'd be happy to work with the developer in testing any updates that 
might fix this.

Thanks for the initial support of this chip.
