Qlik recently launched the new ODBC and SFN connector. This new release lets you connect straight to a variety of database products (including MySQL) without defining a DSN or anything else. It even includes all required drivers.
(Being a partner, you can) Log in into the Downloads portal and select Connector->Qlik ODBC Connector. Check the release notes for more details.
