I'm not sure I fully understand, but I think it's not really that complicated -- all you need is the radeonfb driver to receive the suspend request using standard driver model, and power down the graphic adapter using standard PCI methods, or do any card-specific wizardry, which, as you implied, should not be difficult to implement. A similar thing should be done at resume et voila, you get the display back on.
