Is it possible to dope the coil with something to damp out the whining? I have an old Lenovo that has this, and the noise seems to vary depending on what's onscreen. It can be very annoying.

Manufacturers often apply some goopy glue on top of inductors to damp out some of the noise, like this: http://i.stack.imgur.com/144ui.png
Yeah, I've done this myself when building switching power supplies. I guess there's no reason not to tray silicone or nail varnish on noise graphics cards.
