If you build a cpio rootfs, you shouldn't need any additional command line
parameters because the kernel never gets to mounting the root filesystem. It
just runs the /init in the initramfs.
Using a cpio rootfs should also solve your problems with the device nodes,
because we provide a /init that mounts devtmpfs explicitly.
