Binary package hint: xorg

Change grub setting to radeon.modeset=0 allows system to boot with no known issues.

Also tested with the following

(grub) radeon.modeset=0
stop gdm
rmmod radeon
modprobe radeon modeset=1

same issue as above, no graphics, system still responsive (ssh) bug report was ran in this state.
