I can’t remember how I stumbled on this link, or when the page was even published, but if you are interested in installing a Linux distro other than Gentoo or Fedora on your PS3, you will be good to take a look at this guide for installing openSUSE.
Personal experiences with Linux on the PS3 have been good. I’ve had Gentoo on mine for the past few months and dabble with it every once in a while. I have mine set up to run an NES emulator which I can control with the PS3 gamepad, although that took a fair amount of hacking and tweaking to make function properly. Regardless, it would be nice if Sony opened up more and offered full support of the CPU and on-board graphics as well, since the console itself is very slow with normal PC tasks, despite having a blazing-fast Cell processor.
