xorg.conf, Xorg.0.log, xrandr --verbose output

Overview:

Using a Radeon X300 card, and upgrading from version 6.8.0-12.fc9 to version
6.12.2-14.fc11 of the radeon driver (and to xorg-server 1.6.1.901-1.fc11),
xrandr ceases to put the x-server into dual head mode, but only allows the
monitors to mirror one another, displaying either the left or right hand side
of the virtual desktop.

Steps to reproduce:

On a system with an X300 card, running an unmodified Fedora 11;

1) Generate "base" xorg.conf: Xorg -configure
2) Modify to add "virtual 2560 1024" virtual desktop configuration
3) (Re)start Xorg
4) Issue command to configure dual head:

xrandr --output VGA-0 --auto --crtc 0 --pos 0x0 --output DVI-0 --auto --crtc 1
--right-of VGA-0

5) Observe monitors in cloned mode, showing left hand side of stretched virtual
desktop, and xrandr --verbose indicates both monitors connected, using
different CRTCs

Further steps to resolve:

1) Downgrade the following packages to Fedora 9 versions:

xorg-x11-drv-ati -> 6.8.0-12.fc9
xorg-x11-drv-keyboard -> 1.3.0-3.fc9
xorg-x11-drv-mouse -> 1.3.0-2.fc9
xorg-x11-server-Xorg -> -1.4.99.901-29.20080415.fc9

2) ln -s libcrypto.so.8 /usr/lib/libcrypto.so.7
3) Repeat steps 1 to 4 above to get dual head, stretched desktop operation

(Unfortunately, this seems to have the side effect that the Xorg runs busy)
