We can try to use each DGA driver only with corresponding version of
DGA extension.  What does XF86DGAQueryVersion (or similar) return for
DGA2?  We can add tests for specific version in detection routine for
both drivers and fail autodetection, if version is not supported.

had no time to search for it yet.
