As requested by some users. Here’s a first image based on Ubuntu 13.04 with XBMC Frodo 12.2. This image is an Nvidia and Intel only. Within 13.04 the AMD drivers are broken. Please use at your own risk!
I also compiled a ubuntu image with the XBMC packages from wsnipex. This version contains many stability improvements as well some performance and framedrop improvements over de generic XBMC version. More details can be found over here: http://forum.xbmc.org/showthread.php?tid=116996
