I have updated the wiki for creating ARM images:
https://fedoraproject.org/wiki/Architectures/ARM/Installer
This includes instructions for creating images using livemedia-creator
on F17, and the kickstart files used for Panda, Trim Slice, and
Versatile Express. I will be adding kickstarts for XFCE images as soon
as they are complete (tested).
