I'll keep looking around as well(the best I can)

FWIW not sure if this means anything but


grep PS *.dsl

gives:


SPST,   1,
         PSVT,   8,
         PSCL,   8,
         APPS,   1,
                         PSI0,   8,
                         PSI1,   8,
                             If (PSI0)
                             Store (0x00, PSI0)
                                 Return (CRS (PSI0))
                                 Return (CRSI (PSI0))
                                 Store (SRS (Arg0), PSI0)
                                 Store (SRSI (Arg0), PSI0)
                             If (PSI1)
                             Store (0x00, PSI1)
                                 Return (CRS (PSI1))
                                 Return (CRSI (PSI1))
                                 Store (SRS (Arg0), PSI1)
                                 Store (SRSI (Arg0), PSI1)
                 Method (_PSW, 1, NotSerialized)
                 Name (PSIT, 0x00)
                     Method (_PS0, 0, Serialized)
                     Method (_PS3, 0, Serialized)
                     Method (_PS0, 0, Serialized)
                                 Store (0x00, APPS)
                     Method (_PS3, 0, Serialized)
                                 Store (0x01, APPS)


there's no such thing as a PS/3 is there?
