How pass -ignoreABI to Xorg from GDM?

I successfully install nVidia drivers and prevent nouveau loads.

Almost all works fine, but when gdm try to start a X server fail with this message:

cat /var/log/Xorg.0.log |grep -e EE -e WW

[    88.641] (II) Loading extension MIT-SCREEN-SAVER
[    89.149] (EE) NVIDIA(0): This video driver ABI is not supported.
[    89.149] (EE) NVIDIA(0): Use the -ignoreABI option to override this check.
So, I manually start Xorg with the -ignoreABI and works fine.

Xorg :0 -ignoreABI
But I can't start Xorg from GDM, I try put

Section "ServerFlags"
 Option "IgnoreABI" "1" 
in /etc/X11/xorg.conf

also try put

command=/usr/bin/Xorg -ignoreABI
in /etc/gdm/custom.conf

But don't works, How can I pass the -ignoreABI argument to Xorg from GDM and start normally?

Finally, I found this bug.

So, I hope there is another way to pass arguments to Xorg from GDM, I don't want install kdm

Here's the ServerFlags section of my xorg.conf file. Hope it helps
Section "ServerFlags"

# Uncomment this to disable the <Crtl><Alt><Fn> VT switch sequence
# (where n is 1 through 12).  This allows clients to receive these key
# events.
#    Option "DontVTSwitch"
# Enables mode switching with xrandr
# There is a report that this can cause Xorg not to work on some
# video hardware, so default is commented-out...
# but i want to use it in xorgwizard so leave on...
        Option      "RandR" "on"
        Option      "AIGLX" "on"
        # added the following per
        #Option      "ignoreABI" "true"

I also try

Option      "ignoreABI" "true"
But don't works, It looks like more a problem of how GDM call Xorg inside the source-code, and the lack that can't load values from /etc/gdm/custom.conf

Here's my thread in FedoraForum
