I have just finished building a KDE3.5 LiveCD for Kubuntu 9.04 Jaunty, available here: http://apt.pearsoncomputing.net/cdimages/  Currently, only the i386 image is available for download, but I am working hard to compile the amd64 version as well.

Are there any brave souls willing to try this image out and give me some feedback as to the installed program selections, stability of live and installed systems, default theme, etc.?
  If so, please report back to the kubuntu-kde3.5-users list or file some bugs! :-)
