People sometimes still think they can enable UMS by specifying
radeon.modeset=0 on the kernel command line, but UMS support was
removed years ago and the driver just fails to load when the option is
specified.
If the driver shouldn't load at all then this can be easily done with
modprobe.blacklist=radeon on the kernel command line.
