You'll notice the 12345 part in the line. That means load that when you're in one of those init levels. Thing is, I think that with the way we boot, you may still be in S (single user). So, what ali says is probably necessary (the console= line). Doing a higher value like 115200 means that it will print at that baud rate which means that characters will appear faster.
