This is the list of calls to turn on/off the switchable graphics card in Linux so far:
status = acpi_get_handle(root_handle, "\\_SB.PCI0.P0P1.VGA._OFF", &handle);
status = acpi_get_handle(root_handle, "\\_SB_.PCI0.OVGA.ATPX", &handle);
status = acpi_get_handle(root_handle, "\\_SB_.PCI0.OVGA.XTPX", &handle);
status = acpi_get_handle(root_handle, "\\_SB.PCI0.P0P2.PEGP._OFF", &handle);
status = acpi_get_handle(root_handle, "\\_SB.PCI0.MXR0.MXM0._OFF", &handle);
status = acpi_get_handle(root_handle, "\\_SB.PCI0.PEG1.GFX0._OFF", &handle);
status = acpi_get_handle(root_handle, "\\_SB.PCI0.PEG1.GFX0.DOFF",
&handle);
If you haven't tried the switchable graphics feature in Linux yet, have a look at your DSDT.dsl file. With a bit of luck, you may be able to identify one of the methods above.
