Getting this to work was a rather annoying process, as countless threads asking for help attest to. I somehow trial-and-errored my way to a configuration that works better than ever before, including a 2640x1440 resolution on the DVI port that exceeds the maximum listed in Intel's specs. Even SideCar works!
Here's the relevant section of config.plist:
I'm using ig-platform-id 193B0000, not the recommended 1912000. The latter would either just turn black during boot, or not allow any resolution above 1920x1200. (Had I known that to be the official maximum, I would have probably stopped trying at that point. Ignorance is bliss!)
Also setting device-id and using the complete-modest option. I added both at the same time, and it's therefore possible that either one is enough to get it working. But I'm not going to touch it for a while just to find out.
Update: I updated. Regular installation of the Big Sur Public Beta Update from 10.15.5 worked with no actual problems. Somewhat nerve-wracking due to many reboots, several long phases without visible progress, and lots of scary messages scrolling by fast.
