It depends on what level you're looking for. In theory, the kona card should be producing a balanced signal (no gamma or color cast), so the only calibration you should have to deal with is the monitor itself. This can be dealt with at varying levels.

You could do a basic calibration on your own. First generate color bars from FCP. Setting up an HD timeline and dropping HD bars and tone onto the timeline should produce a rec709 accurate color bars, whereas setting up an SD timeline and generating/dropping in SD color bars should give you a rec601 signal. (If anyone knows the FCP bars to be non colorspace specific/accurate, please correct me.) I'm suggesting going through the timeline/canvas rather than viewing direct from the viewer because my experience has shown the viewer to be color innacurate. Although It might work fine. I expect that the monitor can handle multiple profiles, so you can do separate calibrations for each color space.

Once you have the bars up, you can use them to calibrate your monitor. Doing a google for "calibrate monitor color bars" will show you how to use the pluges to adjust lunimance and blue channel only to adjust saturation.

If you need something more precise, you'll need to bring in an engineer. I'm a big fan of ISF engineers (google them). Basically they will bring in a photospectrometer which allows them to bring you into a far more accurate range.

Good luck.
