Having looked at the current DVB drivers, it does look like a perfect
match.

The DVB USB layer already has the firmware uploading code for Cypress
chips, so that part is dealt with. We could also use one of the existing
drivers to base things off.

But, and it's a big but, without the Cypress firmware for this device,
we're stuck. As all the other DVB cards have firmware. I've asked
Cielplus for this, but haven't heard back yet.
