-===== radeon =====
-  * Expects pre-SI GPUs ((HD6000 series and lower, and non-SI HD7000 series))
-  * For SI, CIK, and newer GPUs, use ''amdgpu'', along with enabling ''si_support'' and ''cik_support'' respectively for the ''amdgpu'' kernel module ((see ''modinfo -p amdgpu''))
-  * :!: Using the ''radeon'' DDX driver caused StepMania to crash with any fullscreen mode on openSUSE TW
-  * :!: This caused a blinking black screen and GDM unable to start on Ubuntu 20.04.1
