There was some discution about this in the DRI mailing list, and i am also currently writing a driver which would need this kind of thing. I guess that you can tell the driver via the device section that it is to share the Framebuffer between monitors and that you can then use the viewport on the display subsection to set the viewport to wherever you want. Now, if you want one of the viewports to do some scaling too, either because your LCD monitor is fixed size, and a program want to run in another size, or for having one viewport displaying a zoomed part of the other or whatever. I think this is not currently possible, but i may be wrong. Also it would be nice if we could follow a window with a viewport, and adjust the zoom factor accordyingly. BTW, is it normal that SDL games requesting 640x480 try to set it even if i did only specify 1024x768 in the monitor modes, and thus give blank screens ? I observed this both in my being worked on driver and in the vesa driver (using frozen-bubbles and solarwolf in fullscreen mode).
