Screenshot on CEDAR with gallium HUS

It is actually not necessary to recompile the module, all is needed is 

  echo "options radeon lockup_timeout=100000" > /etc/modprobe.d/radeon.conf

and then reload the module (or reboot). 

With that the shadertoy runs at 0.086 FPS (see screenshot), which means the
shaders are simply to heavy for the hardware to handle within the default
timeout of 10s.
