If we have a VGA-capable graphics adapter that we support, we should prefer it over any legacy VGA because we wouldn't use it in legacy VGA mode in this case. This solves the problem where we would only use the legacy VGA card when both a legacy VGA card as well as a VGA-mode capable adapter is present.
