Well, your initrd boot scripts could just create /dev/console for
you. However, there is a better solution to this: replace the call to
open(2) in init/main.c with code that allocates a file and calls
chrdev_open() directly. That way, even if /dev/console doesn't exist
on a non-devfs system, there are no problems.
