In addition, asus_atk0110 loads but leaves no trace in dmesg when loaded.

That's good ;-) The driver is quiet when everything is ok. You should
see the corresponding entries under /sys/class/hwmon/hwmonN; upgrade
lm-sensor package to version 3.1.1, older versions do not support ACPI
devices.

Motherboard is an Asus M2N32-WS. DSDT attached.

From a quick glance it should work. If it doesn't enable
CONFIG_HWMON_DEBUG_CHIP.

Well, I just tried it here and it works here too, on 3 different
asus motherboards. But asus_atk0110 is far less useful than the
it87 variant. Yes atk0110 shows correct labels for various sensors,
but for one there's no way to control fan speeds using it, at least
not currently, -- something which is done by it87 easily.

Well, one more difference is that atk0110 also shows vcore, which
at least looks real instead of fake 1.55V as shown by it87.

But anyway, loading the driver just to get correct labels and
vcore seems a bit overkill...
