The App.config API is System.Configuration: http://msdn.microsoft.com/en-us/library/gg145027.aspx. But that won't get you anywhere by itself; the <startup useLegacyV2RuntimeActivationPolicy="true"> setting is used when the CLR creates the main AppDomain. To programmatically change this, you'd need to start your own AppDomain with the desired config. There is already an open feature request to support this: http://ironpython.codeplex.com/workitem/26165.

As a work-around, make a copy of ipy.exe source (very tiny), adding your custom configuration file, and build it ... using that version of ipy.exe to run your IronPython code that depends on the custom config.
