VGN-Z21WN DSDT dump

Apprently _EJ0 waits for undock to complete:

           Method (_EJ0, 1, NotSerialized)  // _EJx: Eject Device
            {
                UDKR =3D One
                Wait (UDKE, 0xFFFF)
                Reset (UDKE)
                Notify (^^PCI0.EXP4, Zero) // Bus Check
            }

On my system, this returns only after I remove the machine from the dock.

Full DSDT attached.
