There is the alternate solution of assuming that EDID is correct, and provide an override when it isn't. So anyone with a good monitor get a nice display by default. Those with a defective lying monitor may have to add a "resolution=640x480" parameter to their kernel command line to get out of the black screen modus. This shifts the bother to those with a bad monitor, who then are free to get pissed off at their monitor vendor . . .
