Make a separate directory in /mnt/us/ called swap:

mkdir /mnt/us/swap
cd /mnt/us/swap

Make a new swap file:

dd if=/dev/zero of=swapfile bs=1M count=128
mkswap swapfile

Turn the file into a block device:

losetup /dev/swap /mnt/us/swap/swapfile

I made some scripts in /mnt/us/swap/ for easy swapping on/off:
swapon.sh

Spoiler:

mknod /dev/swap b 7 8
losetup /dev/swap /mnt/us/swap/swapfile
swapon /dev/swap

swapoff.sh

Spoiler:

swappoff /dev/swap #You don't really need a script for this, but I'm lazy

Swap on...swap off Sounds like wax on, wax off from the original Karate Kid, if you know what I'm talking about

but the commands swapon and swapoff dont work on the Kindle 4, i havent tried inside the chroot yet.
