[Users] Node register bug work around

I realise there is a bug open for a problem where nodes can't register with engine (https://bugzilla.redhat.com/show_bug.cgi?id=782663). However is there any way to easily work around this problem for now. If I add it from the UI it will try to install the node rather than just registering a pre installed from iso node. Is there anyway of registering it from the management machine without it trying to install? I realise the answer might be to hold on for the fix to be commited but if there is an easy way then that would be good.
