I finally found the problem. You were right, it was an issue with my 
modprobe config. I had an old file /etc/modprobe.d/display_class.conf 
that blacklisted the display device:

install pci:v*d*sv*sd*bc03sc*i* /bin/true

Removing this file, there is no need to load the radeon module in 
/etc/modules.

I guess you should mark this bug as invalid.

Thanks for your help.
