.. with a bit more pondering try the old /sbin/e-smith/signal-event ibay-modify to reset the ibay perms.
Ultimately try:
/etc/e-smith/events/actions/conf-horde-startup 
/etc/e-smith/events/actions/conf-turba-startup 
/etc/init.d/mysql.init 
/etc/init.d/mysqld restart 
If that doesn't work, try adding 
/sbin/e-smith/signal-event post-upgrade 
/sbin/e-smith/signal-event reboot 
If none of this works then I'm outta ideas
