The temperature is read from some isa io port at 0x295...

I'm wondering if you should use mbmon instead of ACPI
(the _TMP method in that DSDT look a little ugly to my eyes,
though I am not sure if it will give some buggy
informations).

Maybe you should try to disable acpi thermal stuff via
hint.acpi_tz.0.disabled="1"
and use the mbmon port for monitoring those temperatures. Don't
use ACPI and mbmon at the same time: there will be some conflicts
accessing the sensor chip internal registers.

As an added 'bonus', you should have access to motherboard temperature,
not only CPU, and you should be able to monitor voltages, fan, etc.
