Why? It already does this at driver boot time.

You'll have to ask TI. They'll probably want an NDA.
Their current libraries also are closed source and not compatible 
to any GNU binutil formats.

It basically shows you how to load a program into the card and 
how to start it.
I was hoping somebody else would do some work on it, including some
reverse engineering :-)
I really can't do any more on this myself without breaking NDAs.

Together with the AV7110 datasheet one can at least play a little 
with an ARM7TDMI core and some of the other hardware. Most basic 
developer kits with ARM7TDMI don't offer more than that and are 
much more expensive than the DVB card.
