Integrating Sitefinity with custom db resource provider

As part of Globalization, we are using a custom db resource provider to fetch all resources. The resource keys and the values of the Sitefinity are in .resx files.

We want to have the Sitefinity resources still be retrieved from .resx files, while the resources related to our application should be retrieved from the database. We made the following change in the web.config file:
<globalization resourceProviderFactoryType="Our.DbResourceProvider">

The moment we add the above line, all request to the resources are directed to the database and the Sitefinity related resources are not found in the database. Hence we get resource not found error.

Please advise how to override the above configuration setting so that Sitefinty always retrieves the resources from the .resx files.
