Uhh, the whole point of a journal is that when the computer goes down hard and doesn't have a chance to clean up. If you put the journal on a ramdisk, you might as well just mount it as an ext2 filesystem and be done with it. Without the journal _on_disk_ you get no data or filesystem reliability advantages. If you're after speed, just forgo the reliability or buy better disks.
