It might help to know that the Linux kernel defines some of these as
/* Creator ioctls */
#define FFB_IOCTL ('F'<<8)
#define FFB_SYS_INFO (FFB_IOCTL|80)
#define FFB_CLUTREAD (FFB_IOCTL|81)
#define FFB_CLUTPOST (FFB_IOCTL|82)
#define FFB_SETDIAGMODE (FFB_IOCTL|83)
#define FFB_GETMONITORID (FFB_IOCTL|84)
#define FFB_GETVIDEOMODE (FFB_IOCTL|85)
#define FFB_SETVIDEOMODE (FFB_IOCTL|86)
#define FFB_SETSERVER (FFB_IOCTL|87)
#define FFB_SETOVCTL (FFB_IOCTL|88)
#define FFB_GETOVCTL (FFB_IOCTL|89)
#define FFB_GETSAXNUM (FFB_IOCTL|90)
#define FFB_FBDEBUG (FFB_IOCTL|91)
Other than that, my only suggestion is that there might be a package on
your installation CDs that defines these.
