Dach:

Based on recent experience, I found the following to work with my board and
a 2.6.25-rc2 kernel:

% mkfs.jffs2 -n -e 16 KiB -b -d /export/haleakala -n -o root.img -s 512 -p
  512

# flash_eraseall -q /dev/mtd9
# nandwrite -q /dev/mtd9 root.img
# mount -t jff2 /dev/mtdblock9 /import

So, based on your steps above, it looks like you might meet success by
replacing 'flash_erase' with 'flash_eraseall' and 'dd' with 'nandwrite'.
