-- passing serial params to the kernel in grub.conf should be all it takes
with the CentOS 6 initscripts
In the past I incorrectly configured both and they fought (caused a
feedback loop). Tail /var/log/secure and you'll find invalid logins every
couple of seconds if you have this type of feedback loop. :)
In most of my cases, the feedback loop only seemed to begin when I
disconnected from the serial console (Serial over LAN).

If you want Linux kernel boot output redirected to serial, the grub.conf
modifications are necessary. BUT if you just want a getty listening once
the machine is fully booted, a separate serial initscript is worthwhile.
