SharePoint 2003/2007 granular recovery is available in NetBackup 6.5.2 today not 6.5.3. Exchange 2003/2007 granular recovery will be available in NetBackup 6.5.3.
It's probably worth mentioning also that the granular recovery is brand new patent-pending technology. The granular recovery works with 1-backup opposed to the existing 2-pass backup that gets used today for granular recovery.
RealTime 5.5 should read RealTime 6.5 also.
