This won't help for the root partition, because at the time the fstab is
read, the root partition /is/ already in use. How could you read fstab
if this was not the case? At that time the root partition is only
remounted according to what fstab says. I think you need some kind of
kernel parameter so the kernel knows to use data=journal when the root
partition is mounted the first time.
/usr/src/kernel-source/Documentation/kernel-parameters.txt says
something about a "rootflags" option so set the root fs mount options,
so I think adding
rootflags=data=journal or
rootflags="data=journal"
to the boot loader config could work.
