I pulled the DSDT for the Asus U30JC, for suspend/resume, there are
two methods, _PS3 and _PS0:

echo '_SB.PCI0.PEG1.GFX0._PS0' > /proc/acpi/call

or

echo '_SB.PCI0.PEG1.GFX0._PS3' > /proc/acpi/call

        Method (_PS0, 0, NotSerialized)
        {
            \DIAG (0x70)
            Store (Zero, \_SB.PCI0.GFX0._PSC)
            If (LNotEqual (\_SB.PCI0.GFX0.DGPS, 0x00))
            {
                \_SB.PCI0.PEG1.GFX0.DON ()
                Store (Zero, \_SB.PCI0.GFX0.DGPS)
            }

            \DIAG (0x71)
        }

        Method (_PS3, 0, NotSerialized)
        {
            \DIAG (0x72)
            If (LEqual (\_SB.PCI0.GFX0.P3MO, 0x01))
            {
                Store (0xC0, HPD)
                \_SB.PCI0.PEG1.GFX0.DOFF ()
                Store (0x03, \_SB.PCI0.GFX0._PSC)
                Store (0x01, \_SB.PCI0.GFX0.DGPS)
            }

            Store (0x00, \_SB.PCI0.GFX0.P3MO)
            \DIAG (0x73)
        }
