This BIOS makes heavy use of TRAP's into SMM, Windows version-specific hooks,
and WMI -- all bad news for Linux.

But OSI(Linux) itself is a NOP on this box, since LINX is set and never referenced, per below.

        {
            If (DTSE)

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