Question Unable to Change Display Resolution

So, I just formatted and installed Fedora 8
I went into the System > Administration > Display and manually set the monitor to LCD 1280 x 1024
(My monitor is a Sony 19'' - SDM - M81)
I rebooted, and my monitor was screwed up :S
Basically, it said 'out of sync' in a box that looks as though displayed by the monitor hardware, not the OS. This text goes away soon after though. The displayed screen is too big for the monitor, going past the edge of the screen.
I go to System > Administration > Display, type in my root password, and then no further GUI appears. Run as root, and I do the same, and nothing appears when I try to open display.
I download and install the latest drivers for my Video Card. (Radeon X1600)
Same thing, no avail, tried rebooting but nothing changes.
Log into the terminal as root.
Here's what I ran:
[root@localhost gt4user]# xrandr -q
Screen 0: minimum 640 x 480, current 1400 x 1050, maximum 1400 x 1050
default connected
   1400x1050       0.0  
   1280x1024      61.0  
   1152x864       60.0  
   1024x768       61.0  
   800x600        61.0  
   640x480        60.0  
[root@localhost gt4user]# xrandr -s 1024x768
Size 1024x768 not found in available modes
[root@localhost gt4user]# xrandr -s 800x600
Size 800x600 not found in available modes
Huh, I say to myself. Any suggestions?
Any help would be greatly appreciated

During installation, Fedora may have set up more than one screen resolution. You can usually cycle through them (they are listed in /etc/X11/xorg.conf). To cycle through the settings, try 'ctrl alt -' or 'ctrl alt +', using the minus and plus keys on the number pad.

I seem to have found the shortcut.
Though, as I filter through the resolutions, none of them fit the screen perfectly. They all seem to have about an inch or more overflowing the side and bottom of the screen.
I tried this before and after going into /etc/X11/xorg.conf as root and editing the Section "Monitor" ModelName.
Here is my xorg.conf file:
# Xorg configuration created by system-config-display

Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"

Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us+inet"

Section "Monitor"
Identifier "Monitor0"
ModelName "LCD Panel 1024x768"
HorizSync 31.5 - 64.0
VertRefresh 56.0 - 65.0
Option "dpms"

Section "Device"
Identifier "Videocard0"
Driver "vesa"

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
