I am currently working on a layer which provides all the necessary
drm glue code for simple framebuffer devices. My test driver is a
Freescale i.MX framebuffer driver. This currently has < 500 loc which
is less than the corresponding driver under drivers/video. I am not
crazy enough to implement a vesa KMS driver, but my hope is that
these tasks can become quite easy with such a layer.
