I would use 'rpm -Uvh <packages> --repackage'  This will make an rpm 
(located in /var/spool/repackage) of what you have in place before the 
upgrade, which should include any modifications to any files distributed 
with the rpm(s) in question.  Beware that this new rpm will not be signed 
by Red Hat, nor will its signatures match.  If you have not changed 
anything, I suppose it doesn't buy you a lot to do this instead of 
reinstalling your original rpms, assuming you still have them.  Either 
way, I would make sure to backup with mysqldump before you do *any* rpm 
changes.
