Boot the box.
then you can start debugging.
Check the x.0.log xorg log file, see if the ati kernel module is loaded and running, try starting X manually so that you can see if any warnings are presented on screen.
Runlevel 3 isn't single-user, that's runlevel 1. 3 on Fedora/Redhat is multiuser without starting X, but enough splitting hairs... 
From runlevel 3 I can do startx and I get a display, although it seems gnome-wm isn't running since titlebars are missing from all windows (running twm at the moment just to be able to move windows about!). The Xorg.0.log file contains the following warnings:
Code:
(WW) fglrx(0): ***********************************************
(WW) fglrx(0): * DRI initialization failed! *
(WW) fglrx(0): * (maybe driver kernel module missing or bad) *
(WW) fglrx(0): * 2D acceleraton available (MMIO) *
(WW) fglrx(0): * no 3D acceleration available *
(WW) fglrx(0): ********************************************* *
however, doing a grep for "fglrx_drv.so" on it yields only the line:
Code:
(II) Loading /usr/lib64/xorg/modules/drivers/fglrx_drv.so
so I presume the kernel module is running. Possibly worth pointing out is that some of the Gnome applets (such as Screen Resolution) do work but others (such as Display) do not. Given that those and gdm don't seem to run, is the problem somehow to do with Gnome rather than Xorg itself?
EDIT: Attempting to run gnome-wm from a terminal fails and produces the following:
Code:
[root@shiro ~]# gnome-wm
compiz: GLX_SGIX_fbconfig is missing
compiz: Failed to manage screen: 0
compiz: No manageable screens found on display :0.0
[root@shiro ~]# gtk-window-decorator: Could not acquire decoration manager selection on screen 0 display ":0.0"
Any clues from there?
