The 0.94 updates/rawhide channel should be populated and ready. You may have to subscribe your system to it via the RHN web interface at https://rhn.redhat.com/
As before, you'll need to have the rawhide key installed - to do this, do 'up2date -u fedora-release' after subscribing to the updates channel, and then 'rpm -Uvh /usr/share/doc/fedora-release-0.94/RPM-GPG-KEY-rawhide'.
