Maybe we should even have an ioctl that returns a list of all mmap'able
regions with some enum type describing it's use (main framebuffer, any of
the dozen special things ffb does, what have you) and even have the X
server use this instead of the hardcoded offsets the drivers now use.

For machfb for example it would return two "main framebuffer" entries,
with different endianess.
