Bug 283231

Intel Coffee Lake (Intel HD Graphics 630) + drm_kmod broken in 14.2

I have been encountering some issues trying to run anything Xorg-related using the drm_kmod drivers (sysrc kld_list+=i915kms) on a brand-new install of FBSD 14.2-Release. 

Attempting to run startx or xinit produces an error "Cannot run in framebuffer mode" (instead of the X session starting).

Said error code is similar to the one posted on this SE post (https://unix.stackexchange.com/questions/615263/cannot-run-in-framebuffer-mode-please-specify-busids), but I don't have the exact one because of the way I fixed it.

Fix: reinstalling on FBSD 14.1-RELEASE seems to do the trick.
