Oh, sorry, those ARE the icons you need, but you have to install the symlink (I thought I did that). So

cd /usr/share/YaST2/theme/current

now

ln -s ../../../icons/hicolor icons

then icons should start popping up

They do, but the result is actually confusing: http://fm.no-ip.com/SS/Suse/YaST/151/y2missingIconsKDE3.jpg

Probably better to have none than random ones missing.

yast2-control-center-qt seems a better solution. http://fm.no-ip.com/SS/Suse/YaST/151/y2IconsQT5KDE3.jpg
