xf86-video-ati-6.7.195 - don't load my customized video mode - and seems to work only with the buggy DDC video modes.

You can do the same things, you just have to do them differently as a
screen can have more than one monitor associated with it.  These
options are documented in the xorg.conf man pages and on this page:
http://www.intellinuxgraphics.com/dualhead.html.  The old config model
doesn't support the new driver model.  The old config model assumes
one monitor per screen.  If you have 3 different monitors attached,
and you specify a set of modes in the screen section of your config,
which monitors do you want those modes to apply to? All of them? One
of them?  Two of them?  And if you specify a mode, what rate and
timings to you want it to use? 1024x768 at 72 @85 @60? reduced blanking?
Once you've associated a monitor section with an output you can add
you custom modes and if you want to use a custom one as your default
mode, specify it using the PreferredMode option:
Option "PreferredMode"  "mymode"

You can also change modes and add new modes at runtime using xrandr.
run xrandr --help to see the options.  To add new modes, take a look
at xrandr --newmode and xrandr --addmode.

the radeon ignore edid option is currently broken, but I haven't
decided on the best fix yet.
