The newer firmware updates don't address VGA EDID detection, at least the documentation doesn't list this.
One thought though, we don't cache the EDID information if it was previously detected? If you switch the screen, does that effectively mean the cable is disconnected on the other computer?
For analog displays like VGA, the drm core polls every 10 seconds or so to see if the monitor is still there since the older analog connctors like VGA do not support hotplug like digital connectors like DVI or HDMI do.
