YaST-UML in SUSE-Linux-10.0

Hello list I seem to have a problem in the oherwise neat new release: YaST-UML doesn't work any more :-( Two packages (um-host-kernel and um-host-install-initrd) has been lost (or, rather they have been assimilated by the other packages), and YaST-UML cannot perform the creation of a virtual host without having then installed. Has anybody the same expirience here? Yours, Thomas
