AAAAAAAAH!!!! i had the same problem! no biggie tho'
you're going to need to edit '/etc/inittab', so open it up in any text editor and look for
a line that says something about default runlevel and change the number 5 to 3, then save, exit and reboot. what u just did was stop FC from starting in GUI mode. once linux boots up, log in as root and type 'rmmod radeon', then 'modprobe fglrx' and now all should be good and well!
if you haven't run fglrxconfig yet, the you have to it now.
type '/user/X11R6/bin/fglrxconfig' and follow the wizard through to the end. if there's any question you're unsure of, just hit enter...except when u get to the monitor horizontal/vertical frequencies, for now just select 31-64 for hor and 50-100 for vert, those setting should work with most if not all monitors at 1024*768@60hz. once you've got X up and running again you can search for the correct settings.
