Rather say something like Disable kernel modesetting. DRM drivers will not perform display-mode changes or accelerated rendering. Only the system framebuffer will be available for use. Requires the firmware or boot loader to setup the display. Useful as fallback, or for testing and debugging.

The nomodeset kernel command line parameter is not documented. Its name is quite vague and is not intuitive what's the behaviour when it is set. Document in kernel-parameters.txt what actually happens when nomodeset is used. That way, users could know if they want to enable this option.
