Or you can enable rpm rollbacks. You can't use yum to do the actual 
rollback but you can use rpm cli for that, yum (or actually rpmlib) will 
create the rollback packages on erasures and upgrades.

See for example http://www.linuxjournal.com/article/7034 and 
http://www.oreillynet.com/onlamp/blog/2006/01/rpm_rollback_in_fedora_core_45.html 
forsome further info on the topic.
