I'm using gentoo with xorg 1.11, radeon 6.14.3.
Try with xorg/radeon/mesa git and same results
Other distro are affected.
With live-cd ubuntu/fedora + gnome/kde/xfce + 32/64 bits same results.
xset dpms force off/suspend/standy don't work.
Instead of switching off, my screen become slowly white.
vbetool switch off the screen but after awake they are have artefacts and the only solution is a reboot.
I've notice that in the log of Xorg I don't have
(II) RADEON(0): DPMS capabilities: StandBy Suspend Off

Can you attach a copy of your vbios? To get a copy of your vbios:
(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom

Copy of my vbios
I have attached my vbios.
Try with and without kms, same results.
I've notice that pm-suspend and pm-hibernate are affected.
My screen turns off, but after 1 seconds he awake, I've a black screen with a prompt and he become white with luminosity at the maximum.
The only solution is a hard-reboot.
But hibernation is apparently functioning because when I restart I've my desktop directly.
Upgrading my bios solve the problem
xset, suspend, works
