I updated my original script to handle removing of swap signatures. I created the test image on jaunty with 16MB USB memory stick by first using mkswap followed by luksformat.

Make sure to read comment #24 before using!

And no, this will not work in jaunty. It's easiest to download karmic live-CD from http://releases.ubuntu.com/releases/9.10/ .
