One way to enable rollback is to set the following value in your 
/etc/yum.conf:

tsflags=repackage

This will place the removed RPM in /var/spool/repackage

I also enable this for the rpm command, by placing the following entry 
in /etc/rpm/macros:

%_repackage_all_erasures 1


This will also place the "erased" RPM in /var/spool/repackage.

I would also recommend setting up a process to prune these packages 
before big patching events to make rolling back easier (ie, no guess 
work on which packages you've updated).
