As stated, because you do not have any device for which this module could be useful.

From ivtvfb.c:
On Screen Display cx23415 Framebuffer driver

    This module presents the cx23415 OSD (onscreen display) framebuffer memory
    as a standard Linux /dev/fb style framebuffer device. The framebuffer has
    support for 8, 16 & 32 bpp packed pixel formats with alpha channel. In 16bpp
    mode, there is a choice of a three color depths (12, 15 or 16 bits), but no
    local alpha. The colorspace is selectable between rgb & yuv.
    Depending on the TV standard configured in the ivtv module at load time,
    the initial resolution is either 640x400 (NTSC) or 640x480 (PAL) at 8bpp.
    Video timings are locked to ensure a vertical refresh rate of 50Hz (PAL)
    or 59.94 (NTSC)
From README.ivtv:
ivtv release notes

This is a v4l2 device driver for the Conexant cx23415/6 MPEG encoder/decoder.
The cx23415 can do both encoding and decoding, the cx23416 can only do MPEG
encoding. Currently the only card featuring full decoding support is the
Hauppauge PVR-350.

NOTE: this driver requires the latest encoder firmware (version 2.06.039, size
376836 bytes). Get the firmware from here:

NOTE: 'normal' TV applications do not work with this driver, you need
an application that can handle MPEG input such as mplayer, xine, MythTV,

The primary goal of the IVTV project is to provide a "clean room" Linux
Open Source driver implementation for video capture cards based on the
iCompression iTVC15 or Conexant CX23415/CX23416 MPEG Codec.
NB Files quoted are in a kernel source tree.
