You can convert an ext2-fs to an ext3-fs rather easy. There are several
examples on the web, like this:
http://www.troubleshooters.com/linux/ext2toext3.htm (boot the nand-system
and convert it from there).

And while you're on the converting trip: convert your obsolete mmcblk0p1
into a swap partition:

mkswap /dev/mmcblk0p1
swapon /dev/mmcblk0p1

For easiness, put it into your /etc/fstab on both nand and sd-card system:

/dev/mmcblk0p1  swap            swap    auto,pri=1              0  0
