Bug#682922: xserver-xorg-video-radeon: Linux kernel 3.5 compiled with kms support but drm report modesetting isn't supported. GPU only supported with KMS, using vesa instead.
Additional information:
When "modprobe radeon" is run, dmesg output is as below. However Vt1 to
VT 6 gets blinking cursor and the original VT7 still remains in vesa
mode with low resolution 1280x1024.
