Since then, I got a laptop with an Intel GPU that has a HDMI 1.4 port. I bought a passive HDMI-DVI adapter to still be able to use the monitor and I could reach 71.017 Hz before the monitor turns black. It seems that anything beyond this value changes the polarity and other parameters and, even though the pixel clock still is below 165 MHz, not even a "Not Optimum Mode" message shows up.

Is the HDMI a limiting factor now, or is something else required for a setup like mine to work with an Intel GPU?

What timing parameters were you using with the NVIDIA GPU? The same timing parameters should work regardless of the GPU, although I'm not sure how Intel handles the 165 MHz pixel clock limit with a DVI monitor.
