fbdevhw provides functions for talking to a framebuffer device. It is os-specific. It is a submodule used by other video drivers. A fbdevhw module is currently available for linux framebuffer devices.
fbdev(4) is a non-accelerated driver which runs on top of the fbdevhw module. fbdevhw can be used by other drivers too, this is usually activated with `Option "UseFBDev"' in the device section.
