I downloaded and built KDE 3.4, and configured my FC3 environment to
use my version of KDE. I can switch back to the Fedora KDE simply by
changing some environment variables. However, having said this, I much
prefer the 'untainted' KDE desktop over the 'unified' look-and-feel of
the Fedora/Redhat desktop.
Fine, switch away from the default Bluecurve style/icon-theme. No need to go (re)build KDE just for that.
