Done, thanks!
And just to be clear: Can I now just copy/paste the following into runme.sh to get custom screensavers?

mntroot rw
mkdir /mnt/us/screensaver
mount /dev/mmcblk0p1 /mnt/base-mmc
mv /mnt/base-mmc/opt/amazon/screen_saver/600x800 /mnt/base-mmc/opt/amazon/screen_saver/600x800.old
ln -sfn /mnt/us/screensaver /mnt/base-mmc/opt/amazon/screen_saver/600x800
mntroot ro

Edit: Or should I follow this tutorial? It seems to be for Kindle Touch though.
