That's strange. Those resolutions should fit within 300 MHz pixel clock, and if you're able to add those resolutions with the NVIDIA control panel, then it's not an adapter limitation. The only thing I can think of that would stop refresh rates from appearing would be if GPU scaling is enabled in the NVIDIA control panel, which you don't want with a CRT monitor. The only other issue that comes to mind is NVIDIA won't read more than 8 standard resolutions, but you said you used detailed resolutions.
