.. 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
