WOW - after following the scripts prefdm -> gdm - somehow gdm was not 
even installed.
Not sure how that can be with a "graphical" install on kickstart and 
asking also @general-desktop
and @internet-browser in my kickstart file.

Anyway when I did "yum reinstall gdm" it said it wasnt installed.
so I did "yum install gdm" and it installed - I rebooted and X is now 
running.

Again - not sure how gdm did not get installed. Maybe I'll add that to 
the kickstart file.
