Actually it works fine in 10.9.2 but it should work in 10.8 (maybe starting from 10.8.3)

You must use layout 28 (0x1C, 0x00, 0x00, 0x00) in your DSDT or change the content of HDEF device in your DSDT like this:
Device (HDEF)
        {
            Name (_ADR, 0x001B0000)
            OperationRegion (HDAR, PCI_Config, 0x4C, 0x10)
            Field (HDAR, WordAcc, NoLock, Preserve)
            {
                DCKA,   1, 
                Offset (0x01), 
                DCKM,   1, 
                    ,   6, 
                DCKS,   1, 
                Offset (0x08), 
                    ,   15, 
                PMES,   1
            }
            Method (_DSM, 4, NotSerialized)
            {
                Store (Package (0x16)
