> Nice that you hooked up libgfxinit!

Unfortunately I've just noticed that, with libgfxinit, the GPU doesn't work after a S3 resume.
> Please provide raminit logs for both failing and working case. Did you try the pending ivybridge raminit patches? They might increase raminit stability.

Unfortunately I can't reproduce the working case, but I can provide you the log of a failed raminit, as soon as I obtain a USB debugger.

PS13, Line 47: * If an external card is inserted and the option
             :     ONBOARD_VGA_IS_PRIMARY is not enabled, the internal GPU
             :     disappears completely from the PCI bus.
> This is the result of the combination of disable_peg() in nb/sandybridge/no

IMO, this is completely an unexpected behaviour, as many users (me included) use both the GPUs. The OEM bios didn't show the integrated GPU as well, which led me to think that my integrated GPU was dead.

I'll give a look at the code and add a NVRAM switch if I can.
