This matches the algorithm used by earlier kernels when selecting the mode for the fbcon. And only if there is no modes at all, do we fall back to using the BIOS configuration. Seamless transition is still preserved (from the BIOS configuration to ours) so long as the BIOS has also chosen what we hope is the native configuration.
