Yes, that should be expected behavior with vesafb.  The adapter was
set very early during the boot process, when machine is still in
real mode, vgacon will never load, and you will only see any semblance
of display until the framebuffer console is loaded.  You should
see different behavior with chipset-specific drivers, ie, you will
have vgacon momentarily until fbcon takes over.
