RV: ttyS0

 Hello :
 You could stop the kernel hogging the /dev/ttyS0 port as the 
 default console as it boots without recompiling the kernel. 
 There is a file called '/etc/inittab', in where you would 
 find these lines:
 # Uncomment the following line to get a console shell 
 Just comment last line with a starting '#':
 # sh:3:respawn:/bin/sh
