I've a video card (ATI 3D Rage) which is configured using the XF3 server during installation. After reboot (did also upgrade to Xconfigurator 4.3.54 which fixes the problems with --preferxf4 - the symbolic link in /etc/X11 was not corrected) I do run Xconfigurator --preferxf4. Afterwards I do a mkkickstart. The file generated contains something like this: xconfig --server "/etc/X11/X: symbolic link to /usr/X11R6/bin/XFree86" --monitor "delld1025he" I don't know what happens when XF4 is chosen during installation (but from what I do see I'd say that kickstart doesn't handle XF4 properly, as XF4 uses --driver instead of --server), however, I'd think it should be a quite normal thing to rerun Xconfigurator before creating the kickstart file, therefore the correct --driver statement instead of the --server parameter listed above should be generated.
