Can you bisect?
I really don't know :-) Haven't done it before. On the other hand, I will surely not have time to do it until next sunday (if I have time next sunday). Sucks, yeah :-/
I suspect the culprit is one of the patches that made the kernel edid parser more strict. Alternatively, you may have been using ums previously which does not have the same strict checks as the kernel.
One simple question: is it possible to get the edid info provided by the VGA port? In that way one could compare both raw outputs.
