I've followed the project for a while, running KDE-Windows under Windows XP (it's amazing that it works at all, that it works pretty well is astounding!)
April 2009 I went and installed Kubuntu on a spare partition. Lots of struggle, documented in /Kubuntu 9.04 setup and problems.
That PC had a built-in sound card and a fancy Audigy ZS. KDE System Settings > Multimedia and ALSA were always confused about them. The Audigy ZS stuttered and screeched. I figured out how to switch them around, details in /Multiple audio devices
