Out of curiosity, is anything being done with this? I'm really
interested to see the PVR working in a modern kernel. I'd like to
help more, but I am afraid I don't fully understand the interconnects
and how the driver componenets interact with the omap processor.

Please let me know if there are sub-tasks that I can assist.
