Issuing ACPI call methods to disable NVIDIA Optimus card

Hello. I have an Asus U36JC laptop which has two graphic cards (NVIDIA
Optimus technology): an Intel integrated card and GeForce 310M. To
save power on Linux I use acpi_call module to disable nvidia card
completely. This acpi_call module
( enables an interface to pass
ACPI methods. Then when I issue

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

I'm disabling the nvidia card. Is something like that possible with
NetBSD? I'd like to use it on my laptop, but unfortunately it gets too
hot when both Intel and Nvidia card are powered on.
