Xorg can't be restarted gracefully running CEDAR graphics card

Description
Running Debian unstable with:
xserver-xorg-video-radeon 1:7.8.0-1+b1
and minimalist /etc/X11/xorg.conf:
Section "Device" Identifier "Radeon CEDAR" Driver "radeon" EndSection
I experience the lockup of the video playback window running mpv (requires kill -HUP from another window to terminate mpv), chromium windows not refreshing unless I switched to vt1 and back to vt7, and
service lxdm restart
failing. I needed to kill -9 the Xorg process to avoid having to reboot to restart Xorg.
Running mesa 13.0.2 and ddx based on Debian version 2:1.19.0-3.0
Video card identifies itself as:
