=== WARNING SHAMELESS PLUG ALERT ===
I looked far and wide for help on installing FC on the PS3. I found only a few obscure guides for other systems and only one that applied to Fedora. So, I made a site dedicated to running FC on the PS3.
http://www.fedora-ps3.com
A simple guide is there, but I hope to incorporate custom kernels, install scripts and even a yum repository to keep current with kernel releases (while probably not realistic until Linux 2.6.20 incorporation into FC6 or FC7 is released).
Anyway, your insights, corrections and contributions are all welcome.
