ATI drivers messing up my display ? (CentOS)


I wanted to setup a game (Cube) on my CentOS box. I noticed the game runs very low on fps and I assumed that was because there was no video acceleration. So I downloaded the ATI driver package: ati-driver-installer-8.23.7-i386.run (31Mb). Everything went fine with the setup, and now the game works well on fps however X seems to be running on a huge resolution (I believe its 1600x1200, which is much bigger than my usual 1024x768 - also the screen refresh rate is so low that it hurts my eyes). I am however unable to revert back to my original resolution because:
- Applications -> System Settings -> Display no longer works (it just doesn't start).
- I've got an ATI Control utility but there is nothing about screen resolution there.
- the command aticonfig --resolution=1024x768 seems to be working (of course I ran that as root), but after I restart X (or reboot) the resolution stays the same (huge).
- tried editing xorg.conf, but still no luck. Below is a section which I consider relevant from xorg.conf:

Code:
Section "Monitor"
	Identifier   "Monitor0"
	VendorName   "Monitor Vendor"
	ModelName    "Philips 109B40"
	DisplaySize  1024	768
	HorizSync    30.0 - 97.0
	VertRefresh  50.0 - 160.0
	Option	    "dpms"
EndSection

Section "Monitor"
	Identifier   "aticonfig Monitor 0"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "radeon"
	VendorName  "Videocard vendor"
	BoardName   "ATI Radeon 9800"
EndSection

Section "Device"
	Identifier  "ATI Graphics Adapter 0"
	Driver      "fglrx"
	BusID       "PCI:1:0:0"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Videocard0"
	Monitor    "Monitor0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1024x768"
	EndSubSection
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1024x768" "800x600" "640x480"
	EndSubSection
EndSection

Section "Screen"
	Identifier "aticonfig Screen 0"
	Device     "ATI Graphics Adapter 0"
	Monitor    "aticonfig Monitor 0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
	EndSubSection
EndSection

Section "DRI"
	Group        0
	Mode         0666
EndSection


What options do I have left ?

PS: My display adapter is an ATI Radeon 9800 SE
PPS: I edited the line
Code:
DisplaySize  1024	768
from the above xorg.conf. It was originally set up to:
Code:
DisplaySize  320	240
