It's not the hybrid GPU option. I have a Sony VAIO CW that does not advertise hybrid GPU functionality, nor is there any information of hacking to an enabled state online.

There was another thread that discovered the EDID is loaded by ACPI _anyway_, and the main laptop screen can be enabled with this:

Code:
Option         "CustomEDID" "DFP-0: /proc/acpi/video/NGFX/LCD/EDID"
Everything related to monitor detection is really messed up on these cards right now.
