Using an HDMI-DVI cable makes it work like single-link DVI, which limits you to 165 MHz pixel clock. The patch is supposed to get around that, but it looks like they added another check in the driver at some point. I will look into that. For now, you should be able to get under 165 MHz pixel clock by reducing the horizontal/vertical totals. Then you won't need the patch at all. Try reducing the vertical total to 1100. If that doesn't work for your monitor, try reducing the horizontal total to 2048 and set the vertical total to 1111. That'll also get you closer to 71.928 Hz.
