Sorry I re-read the code and I was wrong about a crash. The idea here was to make console=fb fallback to the serial port (or whatever the default is in the devicetree) if the framebuffer is not available.
Not sure off the top of my head how to solve this cleanly for non-simplefb drivers, let me think about it...
