[gdm-list] gdm and -ignoreABI for Xorg in Fedore Core 6

[Udo van den Heuvel <udovdh xs4all nl>]

Hello,

To get my Matrox G550 working with dual screens in Fedora Core 6 (with
Xorg 7.1.1) I need to pass the -ignoreABI parameter to Xorg.
When the machine boots by itself it automagically starts X and takes
care of `building` the desktop I use.
Where in the gdm configs can I tell Xorg to use the -ignoreABI parameter
on the commandline?

Thanks and kind regards,
Udo
