Fixed! I read that Intel is pretty much plug and play, so deleted my 
nvidia-generated X config and went with what gets installed by default. 
It now works just fine.

I may need to sort out again how to explicitly load EDID, so as to get 
it to boot cleanly without the AV Receiver turned on, but this setup 
will do for now.

Thanks for the help.
