for openSUSE 10.2 KDE 4 and KDE 3 could be installed in parallel. Now the KDE:KDE4 repository seems to be the base for Factory and the the spec files include "Replaces" tags, which disable parallel installation:
E.g. kde4-ksudoku replaces "ksudoku" package (same for other packages). Could this please be changed, so that these replaces only work for >= 11.0?
