Right, I've not tested GCM with any of the non-free drivers, although
it should work.

Ohh, can you attach the .bin file from gcm-dump-edid please.

Sure, GCM just uses the edid to get the device data for the monitor.

Yes, although I'm not sure GCM will assign the profile and set things
like the vcgt data if you do this. It would be better to fix the
