Your printk() calls need the proper KERN_* level.
And what happens if you can't open /dev/null? (hint, udev enabled boxes usually do not have a /dev/null this early in the boot process). Does this mean we should add a /dev/null to the initramfs image, like the /dev/console node we currently have there?
