You know you can just omit the drm drivers from the kernel, right? For example, on amd64: no i915drmkms* at pci? no radeon* at pci? no nouveau* at pci? #no amdgpu* at pci? # (not even enabled by default on amd64) You can also disable them at boot-time with userconf, and you'll get a dumb pci framebuffer with genfb instead: > boot -c userconf> disable i915drmkms userconf> disable radeon userconf> disable nouveau userconf> quit Same for the Arm boards that use the drm modesetting APIs, like tilcdc(4) and tifb(4). But you'd have to rewrite all those drivers -- and test them on a menagerie of Arm boards where the drm stuff has already been tested and works and has very small maintenance burden at this point. I think you'll find you've misplaced where the painful parts of all this are, but go ahead...
