Looking at the git repository under main/dependencies I find both qt3 and tqt3. The first questions is do we want the build based on tqt3 or qt3? Both look fairly identical.
Next, there were a number of standard kde and arch patches that were applied when I was building last year. I am sorting though them to find what has already made its way into the code. Does anyone have a list of what patches have already been applied to tqt3? For qt3 we were applying the following:
gcc46-arch.diff qt-3.3.8-buffered-iconview.patch qt-3.3.8-eyecandy.patch qt-3.3.8-fix-qtextedit-vulnerability.diff qt-3.3.8-xinerama.patch qt-3.3.8-xinerama-qpopupmenu.diff qt-3.3.8-xmms-dynamic.patch qt-copy-kde-patches.tar.bz2 qt-odbc.patch qt-patches.tar.bz2 qt-png14.patch

The bug report discussions reveal that several of the patches you listed have been merged.
