Hi Mr. Trash,
is that the official Apple GF4MX? Certainly the GF2MX cards are not dual head and will only mirror output, I suspect the GF4 might be the same, especially under OS 9 as the drivers weren't great for these cards. Same goes with wanting 1080p and 720 WS resolutions - you'd be pushing it.
You'd probably have better luck with a Radeon 7x00 or 8x00 card under OS X for dual display, partly because ATI actually gave a damn and their control panel/drivers are better, and more supported under OS 9.
