I'm assuming Hyok added this because it wasn't easy or possible to
change the file system .. I can imagine there are debugging situations
where that's true.

I don't think the kernel is going to implode if we allow an optional
ttyS override for debugging purposes.. I just don't see that "screwing"
up the kernel. I can even embedded that inside the C file, and not make
it a Kconfig option ..
