Re: [lm-sensors] Erratic value of MCH temp. (0C),

Hello Luca,

With your modified version of the driver I have been able to test the
new ATK0110 interface and it indeed delivers a proper value of the MCH
temperature! The recipe of Jean Delvare was invaluable for me.
I have attached the output of the sensors command in both the old and
the new situations.

Now there remains the point of incorporating things properly, so that
one doesn't have to manually re-make the object with every new version
of the kernel headers.

Another point that drew my attention is that the two ATK0110 interfaces
don't agree on the naming of the fan sensors as you can tell from the
two attachments.
Both display 4 fan's, they agree about the CPU fan, but the new
interface assigns one value to a NB fan (North Bridge =? Memory Control
Hub (MCH)). There is no such fan on the Sabertooth board. There are 2
chassis fans and a power fan though.

Thanks so far,

Joris
