Correctly identify such monitors, and use the alternative formula when generating modes for them. Note that we only do this for "standard" timing descriptors (tuples of hsize in characters / aspect ratio / vertical refresh). Range-based mode lists still only refer to the primary GTF curve. It would be possible to do better for the latter case, but monitors are required to support the primary curve over the entire advertised range, so all it would win you is a lower pixel clock and therefore possibly better image quality on analog links.
