I'm really not sure what you're talking about here. AFAIK, you don't
have to change anything but xorg.conf (or create a snippet
in /etc/X11/xorg.conf.d) to configure X to use an arbitrary mode on a
display with no/broken EDID. The relevant parameters may be somewhat
different from what they were five years ago, but they're not
particularly any more or less complex, just different.

You've always needed a Modeline for the mode you want to use in
xorg.conf if your monitor didn't provide one via EDID/DDC. Sure, distros
used to ship with a huge forest of pre-generated Modelines to get around
this, but that was just nasty.
