I'd probably reclassify drivers/video/fbdev/simplefb.c as a skeleton
and use it as a template for making device specific versions of it.

I don't see why there is so much resistance to just making device
specific fb drivers.  Whenever the KMS driver gets written just
disable the device specific fb driver in the build.
