Can you check if rebooting into windows turns the nvidia card on?

It may be that the \_SB.PCI0.PEG1.GFX0.DON method needs to report back to
the _T_0 scope...

Someone modified the acpi_call method to call it with parameters for an Asus
EEEPC laptop (see mailing list archives). It may be that the ASUS U30JC
model needs a similar procedure to store the status of the DON and DOFF
method calls.

                                    If (LEqual (_T_0, 0x03))
                                    {
                                        And (Local0, 0x03, Local0)
                                        If (LEqual (Local0, 0x01))
                                        {
                                            \_SB.PCI0.PEG1.GFX0.DON ()
                                            Return (0x01)
                                        }
                                        Else
                                        {
                                            If (LEqual (Local0, 0x02))
                                            {
                                                \_SB.PCI0.PEG1.GFX0.DOFF ()
                                                Return (0x00)
                                            }
                                            Else
                                            {
                                                Return
(\_SB.PCI0.PEG1.GFX0.DSTA ())
                                            }
                                        }

                                        Return (0x01)
                                    }
