More linux switchable methods

We received another method from a UL30JT laptop user, please keep providing DSDT.dsl information in this bug report:
https://bugs.launchpad.net/bugs/312756
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);

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.
