So you are running 2.6.23 or later and gave it acpi_osi=Linux
and just that parem made thermal info show up?

Can you dump the /proc/acpi/thermal_zone files
with and without this parameter?

This is sort of mysterious, for ASL does this:

          If (CondRefOf (_OSI, Local0))
            {
                If (_OSI ("Linux"))
                {
                    Store (0x01, LINX)
                }



    OperationRegion (GNVS, SystemMemory, 0x7F6E2B2D, 0x0100)
    Field (GNVS, AnyAcc, Lock, Preserve)
    {
        OSYS,   16,
        SMIF,   8,
        PRM0,   8,
        PRM1,   8,
        SCIF,   8,
        PRM2,   8,
        PRM3,   8,
                Offset (0x09),
                Offset (0x0A),
                Offset (0x0B),
        P80D,   32,
                Offset (0x10),
        PWRS,   8,
                Offset (0x12),
        LINX,   8,
                Offset (0x1B),


And there is no other reference to LINX in the ASL..
So something like the EC must be accessing this location?

What does the e820 stuff in the beginning of dmesg say about 0x7F6E2B2D?
I'm wondering if GNVS stands for Global Non Volatile Storage...

thanks,
