What I do not know is if modelines will work with various PC ports such as HDMI, display port, etc, connectors.

I guess it will be a suck it and see. I am aiming to go from a VGA connector with a few resistors and a cap into a System A modulator, I have just build the adaptor. I have a few old laptops that have the VGA connector on them to start off with but it would be nice to get it to work with the nvidia cards in this PC.

There is no real reason for modelines not to work with digital video interfaces such as HDMI, DisplayPort and the digital part of DVI. The graphics card driver or electronics may restrict the allowable resolutions and timings though.
DisplayPort and Mini DisplayPort are purely digital interfaces as is HDMI - there are no analogue RGB and sync signals on these.
Note that DVI was deprecated several years ago and will eventually disappear. It seems that DisplayPort and its mini variant are becoming the video interface of choice on current production desktop and laptop PCs.
