Imho, the fbdev should be a separate device from the monitor: fbdev -> fbmon -> EDID The EDID should be a property of the monitor So fbdev should instanciate a monitor object for each head after detection. It's still unclear for me how to deal with the various types of monitors though - EDID available - Mac old style "sense code" available - fixed mode known based on motherboard (old mac laptops among others, probably some embedded) - unknown The EDID shall be used to build a modedb of available modes for this display, the driver doing validation based on that, though a flag to set_var would still be useful to force a mode that doesn't pass validation (EDIDs can be wrong...)
