problem running xf86cfg

[Philipp Bliedung <philipp.bliedung@bliedung.de>]

hi

I just upgraded to XFree 4.0.3 but when I try tu run xf86cfg I get this
error message:

Xserver is running an old XFree86-VidModeExtension version (0.8)
Minimum required version is 2.0
Module ABI versions:
 XFree86 ANSI C Emulation: 0.1
 XFree86 Video Driver: 0.3
 XFree86 XInput driver : 0.1
 XFree86 Server Extension : 0.1
 XFree86 Font Renderer : 0.2
Loader running on linux
Illegal instruction

Any ideas how I can fix this?
BTW what does the VidModeExtension do?

TIA,
Philipp
