KVDR won't work, as you need a V4L-source - or you have to patch it.
(Why not using keyboard directly on a tty?) You also don't have any feedback
of VDR without the OSD. No way to handle things like cutting without OSD!
Andreas Schulz has created classes for OSD2SPU-rendering when he started
his first steps with the DXR3-card. Maybe you can ask him about information
and parts of the code.

I suggest to decode the MPEG/AC3 with the libavcodec-library from ffmpeg,
send the audio to OSS/ALSA, render the OSD (maybe you can even use the
bitmaps created by VDR), overlay the OSD to the video and copy it into the
framebuffer of the graphic-card.
