Meanwhile, you have to remove "1400x1050" from your Modes line to prevent it is used as virtual size for your external display. The internal panel is always connected and 1400x1050 is a valid mode for it regardless if an external display is connected. Setting Virtual 1280 1024 should prevent 1400x1050 mode in principle, the driver doesn't seem to handle this correctly. PanelOff is currently only implemented to turn off display, nothing to do with mode validation. The old driver worked the way you described accidentally, may not be reliable/desired in other cases.
