hmm, 

wouldnt this be the one to avoid, assuming that 'KBC' is KeyboardController?

                Device (KBC)
                {
                    Name (_HID, EisaId ("PNP0303"))
                    Name (CRS, ResourceTemplate ()
                    {
                        IO (Decode16, 0x0060, 0x0060, 0x10, 0x01)
                        IO (Decode16, 0x0064, 0x0064, 0x04, 0x01)
                        IRQNoFlags () {1}
                    })
                    Method (_CRS, 0, NotSerialized)
                    {
                        Return (CRS)
                    }
                }



can you clarify your comment a trifle?

tnx!
