Ok, I think I succeeded in getting the test kernel to install, but it did not solve the issue. The fans ramped up a bit, and I didn't get any errors about DRM on the console, but it still hung on the black screen.
Of course, I may have royally screwed up installing the kernel (thank goodness for Timeshift), so I welcome another, more experienced tester to verify my own findings.
