if the video card you get has DVI out and can support the non-standard resolution that display uses, you should be able to get it to work with a DVI to ADC adapter. i dont think those use any special mac connections on the computer side.
also, if you get it to work but the resolution isnt right, i know of a program for windows that lets you set nonstandard resolutions, but i cant remember the name offhand. if you want it, ill look for it again.
