Need help creating a swap file S-ON android v4.0.3

I'm trying to create a swap file. I run ROEHSOFT Memory Info & Swap check it tells me "your device kernel is not swap compatible."

Anyone know any kernels that are swap compatible I could use to get past this and create a swap file?

phone is a HTC Rezound 4.0.3 S-ON ROOTED

any feedback here will be much appreciated!
