The xorg.conf X -configure generated is just a skeleton, inadequate for your 
hardware. You should probably have system-config-display installed, which 
should do a better job than X -configure did.

http://fm.no-ip.com/Tmp/Linux/Xorg/xorg.conf-i845G-1600x1200x120-gx260-centos55.04 
is from a CentOS 5.5 system similar to RHEL 5.1, on a Dell GX260, which uses 
the same 845G video that your system uses. Hopefully it will work better for 
you than the xorg.conf you have now. It might need tweaking, but should be 
adjustable more to your liking if necessary.
