Problems and things that doesn't work out-of-box noted

• No ext4 filesystem support for kboot, so you can't boot into your fresh install if you select it. Created following report when noticed this little caveat https://bugs.launchpad.net/ubuntu-ps3-port/+bug/365809∞ This can be however solved if you create ext3 /boot partition during install, see following topic http://psubuntu.com/forums/viewtopic.php?f=24&t=1109∞
  
• As mentioned above, it's likely that any of current Desktop install images don't work, please use Alternate install disc images
• swapon -s states that vram swap isn't actually enabled by default. However here's PSUbuntuGPU wikipage that does the trick

What works better than in 8.10?

• Wireless WPA networking works out-of-box
• No actual proofs, but system feels to load much faster than 8.10 and seems to be bit lighter to run after default Gnome install
• Sound through optical workd out-of-box
