So... all I can do with this is get it to mirror the same desktop on two 
different monitors. It does not do for me what I used to be able to do 
with Xinerama. Sad really... I am attaching my xorg.conf. If anyone can 
see what I don't have in it that I should to get one big desktop to span 
two monitors please sing out. Once again this is with rhel4 beta 2 on an 
x86_64. The lspci output concerning video is as follows:

01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AP [Radeon 
9600]
01:00.1 Display controller: ATI Technologies Inc RV350 AP [Radeon 9600] 
(Secondary)

The xorg version is xorg-x11-6.8.1-12.
