As long as your kernel supports it, build the kernel and then run
tune2fs -j and that will create the journal..  If it's mounted it will
still work, you'll just get a cool .journal file while it's doing it.
Once it runs, took about 5 seconds, then change fstab to match ext3 and
reboot.  That's all.

Be sure and test tune2fs and make sure it has the -j option, if it
doesn't you'll have to update your ext2utils.
