Now that simplefb works for me, I finally got around to testing this.
Just a couple of comments:

 * I guess you need to add the modalias "platform:simple-framebuffer"
in addition to the "of:..." one to get module auto loading working.

 * the driver currently doesn't work with your IORESOURCE_BUSY fix to
sysfb (as might be expected(?)):
        simple-framebuffer simple-framebuffer.0: cannot reserve VMEM
        simple-framebuffer: probe of simple-framebuffer.0 failed with error -5

* except for that, fbcon on top of the fbdev fallback support works
fine for me. I didn't yet try the drm driver itself, what clients (if
any) are supposed to work with this, kmscon, weston?
