Well, of course there are going to be monitors that don't have DDC.  But
I'd expect most of the *newer* ones to support it.

I have to add some kind of "override" or configurability into my
radeonfb code, which I've not yet done.  But I think *most* users will
be well served by EDID. :-)  Certainly the flat panels that are on the
market these days all seem to support it well.
