Actually, as I explained earlier, xorg.conf will get trashed in first
install.  For hysterical raisins related to its Debian heritage[*],
we step through all the questions first, and make a decision on whether
or not to make an install *last*.  The only way to guarantee that no
questions will be asked is to write an /etc/default/xorg that sets
XORG_CONFIG=custom (which gets .'ed by xserver-xorg.{config,postinst}),
which will make the debconf scripts bail at the first opportunity.

Cheers,
Daniel

[*]: Debian never probed, so walking through all the questions on first
     install/upgrade was OK.  When we bolted it on, we just threw in
     some magic to preseed the questions, as it were.  The debconf stuff
     still gets run first, *before* the decision on whether or not to
     write a new config file is made.  So, you can have a xorg.conf with
     'I like herring' in it, and it will still merrily ask you about
     the modes if DDC fails or whatever[+], before realising at the end
     of all this, after it's asked a question, that it doesn't need to
     write a configuration file and going away.  This sucks, I know.
[+]: In this case, and then write it out anyway, since it's the first
     install, but I digress.
