Am I missing something? Is there a way to use Jessie with radeon drivers?
Sorry to hear your trouble. Just to put things in order, when you say "I get a working console", could you please dump the output of: $ cat /proc/fb to your email. Also for real complete bug report you could run "/usr/share/bug/xorg/script 3>/tmp/script.log" and attach it here. Finally what is the status of the firmware, just send: $ apt-cache policy firmware-linux-nonfree > 2. Where can I find a downloadable iso for Debian Wheezy PPC?
