The universal frame buffer device is currently supported only on Linux/68k and Linux/SPARC. The plain device accesses the frame buffer at current resolution (Linux/68k calls this file current, e.g. /dev/fb0current); the autodetect one at bootup (default) resolution. Minor numbers 2–23 within each frame buffer assignment are used for specific device-dependent resolutions. There appears to be no standard naming for these devices. Finally, 24–31 within each device are reserved for user-selected modes, usually entered at boot time. Currently only Linux/68k uses the mode-specific devices.

This number is intended for use in sample code, as well as a general ``example'' device number.
