For example I'm looking at making changes to DRM such that DRM will
require the corresponding framebuffer driver to be loaded. If you back
up further this is part of fixing X so that it won't mess with the
hardware from user space. Mode setting would come from the framebuffer
driver instead of the X 2D XAA driver.

Please don't until all the framebuffer drivers are able to deal with
suspend and resume (which will also require some mechanism to switch
backlights back on). Currently, it's far easier to restore some amount
of state on a standard VGA or VESA mode. There's no real support for
doing so with most accelerated framebuffers.
