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
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,
