Have a look at http://www.x.org/wiki/radeonBuildHowTo#TroubleshootingKMSproblems

If you are loading the module after having already started X, then
this might be the only problem. See below.

Edit /etc/initramfs-tools/modules and add the line:

radeon modeset=1

Save the file and run (as root):

# update-initramfs -u

Reboot, this should do it.

If enabling KMS on boot does not solve your DRI problem, please report
back. I had the same problem when I first installed Debian on my home
computer and I have solved it, but I don't remember the exact steps I
took to fix it.

Good luck!
