black screen with Mac version of GTX 680

There is an orthogonal issue apparently with the GTX 680 Mac ROM’ed card versus non-nouveau graphics drivers. I also attempted a manual nvidia driver installation using the recipe described in [url]https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/[/url]. However when I got to the step 2.7 of rebooting after using dracut to rebuild the kernel image without the nouveau driver, I saw the same issue. I assume this means that the vesa drivers currently don’t like the Mac ROMs. Is there any threads here about general linux issues with the Mac ROM’ed card or any place to check whether any additional ROM images beyond the original ones were released by Nvidia?
