Under QEMU and SeaBIOS, everything gets to be printed immediately after "Booting from ROM.." as there is no newline. This prevents parsing QEMU console output for the very first line where it needs to match from the beginning of the line. So add a dummy newline here so the next output is at the beginning of a line.
