yup, i've had enough of all this confusion about the bullet proof X. X
still DOES read xorg.conf, and still DOES apply all the graphical
gibberish we throw in it. i have written my xorg.conf for every
release of kubuntu from the days of gutsy, and always will.
the new bullet proof X is just that it can run, autoconfigure itself,
and work properly even if there is no xorg.conf at all, that's the
whole story. once settings exist, autoconfiguration stops, and it
reads the file. as for xinerama, i'm sorry, but i never used it, or
have any idea what properties/options it has that can be put in
xorg.conf to control it.
