That's because you expect printk() to work even if interrupts
don't (yet), so there's a mini driver in there that works in polled
mode and is completely anatomous (sp?).

Also, the `real' serial driver only works when /dev/ttySx is opened by
a process - it needs a lot of context (file handles etc) that is
dependent on stuff that is only available after the system has booted.
