Why do we need patches in the kernel. Just set you config to
CONFIG_DUMMY_CONSOLE, CONFIG_FB, CONFIG_INPUT and don't set fbcon or
vgacon. Then have a userspace app using /dev/fb and /dev/input create a
userland console. There is no need to do special hacks in the kernel.
/dev/fb is not accelerated, if you want full acceleration use
/dev/dri. Using /dev/dri you can write a fully composited console that
displays dengavi in realtime. This is also a path to getting multiuser
working without a lot of kernel patches.
Not every device has a 3D core!!! DRM is not the answer for the entire graphics
world. Its only for 3D functionality. If you want eye candy without 3D on small
devices use fbdev.
