Does the ubuntu image from rcn.ee have journaling enabled?

Hi Everyone,
I noticed that on my beagleboard xM running Lucid from rnc.ee one of
the SD card lights flashes about twice per second. If the sd-card
comes out facing you it's the light on the right. I was wondering if
this is because of journaling being enabled on the ext3 partition?
Looking at /etc/fstab I don't see noatime. Would you guys recommend I
add noatime? I'm worried that I'm going to kill my sdcard if the
board is constantly writing while idle.

Thanks,
Gabe
