Ah, ok, so you've no (visible) smbus adapters, and acpi thermal management, 
that means that the BIOS has hidden your smbus adapter, this can be worked 
around, but this is a *BAD* idea, as this means that ACPI is using the smbus, 
and we thus shouldn't touch it.

The fact that speedfan under windows does allow you to touch your hardware 
monitoring is not really relevant in this case. We can drive / exposue your 
hwmon IC, but we *really* don't want to.
