If you choose a resolution for a monitor, then by *definition* the scanout area has to be scanned out. Which means, you cannot allocate less pixels than are actually shown. You might have a chance, though, to create a modeline manually, that uses the timings for the native mode, but is only active for a smaller number of pixels. Whether this works with your monitor is doubtful, but it might be worth a try. Most graphics cards can be programmed to scan out a larger area, but only access the framebuffer for a smaller subset - which would be exactly what you want. AFAIR there is no API to provide that information to the driver, or for the driver to provide information about this ability to the server. What you probably *really* want is working shatter support. Which is still in the flux.
