Dual screen using XRandR on ATI 9600 | NV350 AQ (radeon FLOSS driver)

[Torbjørn Thorsen - Nextline]

I'm having trouble setting up a usable dual screen setup with my new 
8.10 installation.

I have to identical monitors running at 1280x1024.
torbjorn at torbjorn-desktop:~$ xrandr | grep connected
VGA-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 
338mm x 270mm
DVI-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 
338mm x 270mm
S-video disconnected (normal left inverted right x axis y axis)

The first problem was the Virtual size was too small to fit two of both 
outputs, so that got configured in xorg.conf.
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 2560 x 1024

So now I should be ready for running dual screen ?
torbjorn at torbjorn-desktop:~$ xrandr --dryrun --output DVI-0 --right-of VGA-0
screen 0: 2560x1024 675x270 mm  96.33dpi
crtc 0:    1280x1024   60.0 +1280+0 "DVI-0" "VGA-0"

The result of doing this is that both outputs end up with the same 
offset, in effect, I can only see the right side of the virtual screen.
torbjorn at torbjorn-desktop:~$ xrandr | grep connected
VGA-0 connected 1280x1024+1280+0 (normal left inverted right x axis y 
axis) 338mm x 270mm
DVI-0 connected 1280x1024+1280+0 (normal left inverted right x axis y 
axis) 338mm x 270mm

I have tried lots of different ways to get them to show the whole 
virtual screen, including using --pos, but I can't get them to split.
The output always see the same area of the virtual screen.

If anybody could point me in the right direction, I would be very grateful.
