I guess it's really not that new either. sorry folks. :)
The new radeon drivers offer a new way to use two monitors. In stead of Xinearama the card creates a virtual destop then uses the two monitors as two viewports. This appears to the system as one big screen and has several advantages over the standard system layout spec.
To set this up you pass special options to the driver which are documented at:
http://ftp.x.org/pub/X11R7.0/doc/html/radeon.4.html
I am running FC5 AMD64 and yum update a couple of times a week.
I have not downloaded the fglrx drivers and they are not on my system and not in yum, I believe because they are propritary.
Anyway the screens display the same thing until X lauches then they both go blank.
After a bit if I move the mouse i see an arrow cursor moving on both screens in tandem.
I have also tried it with all the display sections uncommented and with a modeline in the one with the virutal statement containing a 2560x1024 mode in addtion to the others.
I am going to try a 16 bit depth version of that next.
Has anyone gotten two monitors to work through the raedon driver as documented on xorg with FC5 ?
Any thoughts? :)
I have an all-in-wonder card with the RV350 chip set.
I also have tried a standard Xinearama setup and this did not work.

Here is my xorg.conf

# If you have a US Microsoft Natural keyboard, you can use:

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:

# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"

# If you'd like to switch the positions of your capslock and

I wanted to post and just note that the 16 bit mode did not help.
Also I wanted to note that for one monitor the new Radeon drivers work.
Note however that the FC5 installer uses "vesa" drivers for the Radeon card which did not work for mine. I had to configure it by editing xorg.conf

After FC5 installation find where it says "vesa" and change it to "radeon"

I will note if FC5 test 3 uses the right driver or not. I am installing it over the weekend.
