Thanks for including the info for 4k display users on Big Sur! I was having kernel panics in the installer due to an invalid link rate causing division by zero, and your fix worked perfectly for me. The only issue is that the update.py in the latest release won't allow me to switch the edid. I had to grab the raw version of the update.py in the master branch. If anyone wants to do the fix manually, add
AAPL00,override-no-connect as a data key under the graphics device properties in your config.plist. For the value, copy and paste this EDID:

@xxxzc,

From my understanding, an EDID is how a display identifies itself for the OS. This EDID will force the display to run at 48hz.
You should be able to boot after that fix.
Good luck!
