Note that this is `early userspace', in initramfs. Graphics would be
initialized a bit later than today, but (hopefully) still sufficiently early.
Even right now fbcon is initialized later than vgacon, because we need bus
probing before we can detect graphics cards.
If you really need kernel messages earlier, you have to fallback to vgacon
(ugh), a serial console, or an early boot console (like PPC BTEXT).
