I dont see so much you can change in KDE3 to prepare for KDE4; we usually 
copied the code to trunk, then ran the automatic tool, then made the 
necessary manual work to make it compile, then looked the the code works 
again, and then removed remaining Qt3Support classes.
As to removing Qt3Support, this should be done ultimately, but it is not 
strictly necessary for some cases. For example, we still base our icon view 
in digikam on Q3 classes because a complete rewrite is planned for later, and 
view classes have changed a lot.
The other example would be actions, the move to QAction is necessary and 
should be done while porting (maybe it doesnt compile without, dont know 
anymore)
