Well, I wouldn't expect a truly minimal one to have X at all ;-)  pygtk
and metacity would concern me a little less, mostly due to the fact that
if you're going to use firstboot at all, you have both and you'll be
pretty hard-pressed to really do even another GUI environment with
Fedora tools and not have pygtk.

But for the non-interactive case, it should be pretty trivial to get the
basic bits abstracted into just being in rhpxl and then a simple script
could be used to create the config instead of pulling in all of
system-config-display.  All of the guts should be in rhpxl anyway

It's definitely the right long-term answer.  The question is really how
far along it we can get in the FC6 timeframe, and if we can't get "far
enough", what do we do as a stop-gap.

Right now, s-c-display uses kudzu to try to DDC probe to find out
ranges.  The DB is mostly just for information when monitors lie or to
make things a little bit more user-pretty.
