On MSI Fx600 Doesn't work.

When I wrote "DIS" to /sys/kernel/debug/vgaswitcheroo/switch, I have got 
a blank screen.
echo "IGD" > /sys/kernel/debug/vgaswitcheroo/switch restores screen. I 
don't have running Xorg.
echo "OFF" > /sys/kernel/debug/vgaswitcheroo/switch doesn't switch off 
discrete graphic. No battery time improvement.
Module asus-vgaswitcheroo loaded properly.

But, acpi_call works well.
Trying \_SB.PCI0.P0P2.PEGP._OFF: works!

I think the problem might be with modeset. I don't see 
'/sys/kernel/debug/vgaswitcheroo/switch' when modeset is switched off.

My system is Arch Linux, I updated it today. Kernel is 2.6.38.3.

Here's some logs:
