while someone answers his question , wtf is distroo?
I have Fedora 9 on mine, with a custom built kernel for speed. Ubuntu doesn't work (for most people) past 7.10, with 7.04 being the best until 8.10 is ready (support for the PS3 wavered in Ubuntu after 7.04). Gentoo has a good live cd for the PS3 if you want to try that out. Look in one of the mirrors in experimental/ppc64/livecd/. The Debian live cd has issues with the current kboot/petitboot. Haven't tried YDL - too big for my tastes, and they use e17, which is still not ready for full-time usage.
The main thing is use XFCE instead of Gnome or KDE. There's not really enough memory for Gnome or KDE. Fedora uses a generic PPC64 kernel, and is much faster is you build a custom one (there's instructions in the F9 on PS3 thread in the Fedora Forums). The Gentoo live cd uses XFCE by default, which is another reason it's a good live cd to try.
