>Description:
Up until X.org 7.2 the screen resolution could be set with a
"ModeLine" definition in the "Monitor" section in xorg.conf.
With 7.3 the ModeLine is ignored. X starts in a lower resolution
and flickers badly.
>How-To-Repeat:
Put something like this in the "Monitor" section of xorg.conf:

ModeLine     "1200x960 at 83" 131.00 1200 1204 1324 1588 960 961 964 992
Option       "PreferredMode" "1200x960 at 83"

And repeat the identifier "1200x960 at 83" as Modes in the "Screen" 
section, "Display" subsections. Start X and see it come up
in 1152x768 at 55Hz or something.
>Fix:
Workaraound: Create a subdirectory /etc/X11/xinit/xinitrc.d
and put a (executable) text file in it containing something
like this:

xrandr --newmode "1200x960 at 83" 131.00 1200 1204 1324 1588 960 961 964 992
xrandr --addmode VGA "1200x960 at 83"
xrandr --output VGA --mode "1200x960 at 83"

However, I'm experiencing several issues when using RANDR
to set the resolutions:
 - It only works on the session, i.e. after you log in with
   xdm / gdm. Xdm itself is still displayed in the wrong
   resolution and flickers badly.
 - In the session, mplayer no longer works with XV video
   output. Instead you get a blue window now. X11 output 
   still works, but sucks.
 - In QEMU, when starting Windows, the mouse pointer
   disappears when you click on the desktop which makes
   it unusable.
