Problem with data=journal on root file system.

I am using RedHat 7.2 w/ kernel 2.4.7-10.  My / filesystem is configured
as ext3.  I want to change it to use data=journaled instead of ordered.
If I mount it from a boot floppy, it mounts fine.  (mount /dev/hda2 /mnt
-t ext3 -o data=journal).  I have attempted to find the correct
procedure to start it up as journaled from grub to no avail.  I have
created a new initrd image that works fine with data=ordered.  I see
where one procedure is to use lilo -R linux rw rootflags=journal=update.
I'm confused about the read&write aspect as well as why they used
journal=update instead of data=journal.  This filesystem was created new
with this system, so I should not have to upgrade it.  Thanks.
