I think this behaviour is intentional: userspace is expected to
set the initial mode for non-console frame buffers by using
FBIOPUT_VSCREENINFO.
Otherwise, register_fb() would always set an initial mode on all
framebuffers.
I remember this being discussed years ago (more than a decade)
when the FB layer was relatively new.
