Turning off Nvidia GPU card in Optimus configuration

[Lampshade]

Hi
I was trying half year ago to use OpenBSD 5.5, but system heated my laptop. I have Intel and Nvidia GPU in laptop. I can not disable Nvidia GPU via BIOS. Laptop always exposes and enables two GPUs by default. OpenBSD does not disabled Nvidia GPU, so it heated laptop. I have tried OpenBSD 5.6 and it still heats my laptop. On Linux Nvidia's GPU is disabled automatically. I wanted to find how to disable my card manually, I used acpi_call Linux module (on Linux of course). In my laptop script turn_off_gpu.sh is disabling GPU when I strip methods variable to:

methods="
\_SB.PCI0.PEG0.PEGP._OFF"

and enables when:
methods="
\_SB.PCI0.PEG0.PEGP._ON"

Is there any way in OpenBSD to send first (disabling) command to hardware? It is the only reason I don't use OpenBSD. Maybe somebody can write few lines of code and I will compile kernel for myself?

My dmesg and sensors
Sensors files were created on Generic.mp kernel. File
sensorsWithoutPowerSupply.txt was created 420 seconds after (7 minutes)
disconnecting from power supply. Laptop for 420 seconds was without power
supply. There were 3 xterm windows and one Firefox window with two tabs, but I
didn't browsed internet at the time. I go away for 7 minutes, so laptop was in
idle state.

Hi
I was trying half year ago to use OpenBSD 5.5, but system heated my
laptop. I have Intel and Nvidia GPU in laptop. I can not disable Nvidia GPU
via BIOS. Laptop always exposes and enables two GPUs by default. OpenBSD
does not disabled Nvidia GPU, so it heated laptop. I have tried OpenBSD 5.6
and it still heats my laptop. On Linux Nvidia's GPU is disabled
automatically. I wanted to find how to disable my card manually, I used
acpi_call Linux module (on Linux of course). In my laptop script
methods="
\_SB.PCI0.PEG0.PEGP._OFF"
methods="
\_SB.PCI0.PEG0.PEGP._ON"
Is there any way in OpenBSD to send first (disabling) command to hardware?
It is the only reason I don't use OpenBSD. Maybe somebody can write few
lines of code and I will compile kernel for myself?

acpi_call support would be awesome!
Another use case for it is setting minimum and maximum
battery charge levels for thinkpads newer than xx30 line.

The right way to handle this IMO isn't to provide a generic way to
evaluate arbitrary AML methods. That way lies madness.

A better solution is to create an actual driver for nvidia0 or
whatever and have that driver do nothing except disable the hardware
by evaluating the method referenced above and likely also putting
the device in D3 from the PCI side.

Your diff to implement said functionality is certainly welcome.
