I think this it the correct OleDbConnection signature for .NET 2.0:

System.Data.OleDb.OleDbPermission, System.Data, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089

Maybe the error is occuring becuase you're telling .NET 2.0 to use the
1.1 object.

What happens if you omit the PublicKeyToken and let the Framework
decide which object to use:

 <coonnectionType 
  value="System.Data.OleDb.OleDbConnection, System.Data"/>
