After you run the Quick Repair and Rebuild, does the config_override setting still remain, or is that line removed from this file? Also, after running the repair, please navigate to Admin > System Settings to see if the "Maximum number of Sugar Dashlets on Homepage" setting shows as 100 or something else. What amount of dashlets is Sugar limiting you?
I tested this setting in my own instance and it worked as expected where the setting remained after Quick Repair and Rebuild and logouts/logins and I was able to add more than the default number of dashlets.
