Linux Hybrid Graphics: Using acpi_call module to switch on/off discrete graphics card in Linux

HP Pavilion dm4-1063cl
with Intel (integrated) and ATI (Discrete)
Compiling acpi_call and here's the result:

Trying \_SB.PCI0.P0P1.VGA._OFF: failed
Trying \_SB_.PCI0.OVGA.ATPX: failed
Trying \_SB_.PCI0.OVGA.XTPX: failed
Trying \_SB.PCI0.P0P2.PEGP._OFF: works!

Here is an init script with this to disable the discrete card for now, because the battery drains quicly with the two cards on.

#!/bin/bash
insmod /home/mansor/acpi_call/acpi_call.ko
echo '\_SB.PCI0.P0P2.PEGP._OFF' > /proc/acpi/call
