When you do, make sure they post it to linux-media! FM support is part of the V4L API. We had support for a DAB device, but it turned out that: 1) the driver hadn't worked for ages and 2) the DAB API was never reviewed or documented, 3) the hardware wasn't available anymore, so it was removed recently. I'd love to help create a proper DAB API.
