The option prevents DRM drivers from loading if they could possibly displace a hardware-agnostic driver that runs on the firmware framebuffer. It is a fallback for systems on which the hardware's native driver does not work correctly. After the work on the aperture helpers and their integration with fbdev, it can happen that an fbdev driver replaces a hardware- agnostic DRM driver. Supporting the nomodeset parameter unifies the behavior among the graphics drivers and subsystems. An fbdev driver will not replace any hardware-agnostic driver with nomodeset given.
