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.
