Tired of ttySx and ttyOx

Recently linux-omap integrated omap-serial patches. Now we dont use ttyS2 anymore but use ttyO2. tired of switching kernel versions and fixing my getty, wrote the following
In my busybox /etc/init.d/rcS file:

proc=`mount|grep "proc"`
if [ -z "proc" ]; then
   mount -t procfs none /proc
fi                                                                                         
if [ -f /proc/cmdline ]; then
   # grab console from cmdline and use it..
   tty=`cat /proc/cmdline|sed -e "s/ /\n/g"|grep console|cut -d '=' -f2|cut -d ',' -f1`
   if [ -z "tty" ]; then
           echo `cat /proc/cmdline` "does'nt have console?"
   else
       # remove my previous one if it exists
       rm -f /dev/tty-bd
           ln -s /dev/$tty /dev/tty-bd
           echo "/dev/$tty linked to /dev/tty-bd - using as console"
   fi
else
   echo "cmdline not found - no console?"
fi

In my inittab:
