Default [Q] Swap problem/Kernel - Please Help

Hi all,

i hope i'm right here with my question .

it try do get "Swap" on my phone but it doesn't work.
I have root rights, busybox, cwm , and cm including the werewolf kernel.

I've partitioned my micro sd into 3 partitions.
1. fat32, primary => for my stuff like music etc.
2. ext3, primary => for outsourcing over link2sd and mountfolder
3. linux swap, primary => my "swap" file

if i enter in the terminal emulator:
su
fdisk -l dev/block/mmcblk1
swapon /dev/block/mmcblk1p3

he shows:
swapon: /dev/block/mmcblk1p3: Function not implemented

I tried the way over the app "swapper2" but same result.

I think this could be a swap support problem of the kernel. Does anyone know which kernel (for lg optimus 4x hd) supports swap.

Or have anyone other ideas, how to reach my target?

Kind regards
Daniel
