I would like to be re-assured that the issues that Adam raises are
still possible, perhaps via a different config facility, if there were a fully
xorg.conf'less X in future.  In particular I most definitely would be very
disadvantaged without the vnc module.  Can anyone respond to say how
this module would be loaded when X started if it there is no xorg.conf?

Similarly how would the current touchpad parameter changes to customise
the touchpad be input without an xorg.conf?

I presume that these issues have been thought about even if there is no
complete answer at present? Some idea of what needs to be developed in
order to accommodate these reductions in capability must surely have 
been thought through before the decision to develop X to the point of
not having xorg.conf for F10?
