     Double buffered frame buffer
           Consists of 96 video memory  planes  of  1280  x  1024
           pixels,  including  24-bit  double-buffering,  8-bit X
           planes,  28-bit Z-buffer planes and 4-bit Y planes.

     The driver supports the following frame buffer ioctls  which
     are defined in fbio(7I):

     FBIOPUTCMAP, FBIOGETCMAP, FBIOSVIDEO, FBIOGVIDEO, FBIOVERTICAL,
     FBIOSCURSOR, FBIOGCURSOR, FBIOSCURPOS, FBIOGCURPOS,  FBIOGCURMAX,
