Yep, broken BIOS:

Method (FGET, 1, NotSerialized)
{
    If (LEqual (Arg0, Zero))
    {
        Return (^^SIOR.HWF1 ())
    }

    If (LEqual (Arg0, One))
    {
        Return (^^SIOR.HWF1 ())
    }
}

It always reads the same sensor. The other ("new") monitoring interface
seems fine though. Unload the module and try reloading it with
"new_if=1", like this:

modprobe asus_atk0110 new_if=1

And see if everything looks good.

Luca
