autoyast with suse 9.1

I've read the documentation at http://www.suse.de/~nashif/autoinstall/9.1/html/, and several other sites I found explaining how to create an autoyast.xml file from a complete installation. The instructions for 9.1 don't specify what rpms need to be installed and when I run yast2 autoyast I get: No such client module autoyast I tried installing the modules I found referenced from documents on 8.x (yast-config-autoinst), but I still get the same message. Can somebody point me in the right direction ? Thanks, Todd
