I'd also like to remind you of the existence of http://qt.gitorious.org/qt/kde-qt , a Qt tree to which all KDE developers can commit (you need to have an account on gitorious.org and request kde-developers group membership there), which is shipped by several distributions. (Fedora ships it as a patchset against Nokia's Qt. I know we're not the only ones.)
