I have listened to radio on a TV, but you are of course right. I've
tried finding out how text works on DAB and mostly just came across a
one-line scrolling text capability (as is being used in car radios).
That probably won't be sufficient for reading captions, so maybe
something more like 3-4 lines or whatever is used on TV might be more
appropriate. Again, keen on other people's opinions here.

Note that the technology to transmit captions via HD radio does in fact exist.   NCAM, WGBH and other partners tested such a service in the US in November of 2008.  The tests themselves were successful, and the service was enthusiastically received by deaf and hard-of-hearing audiences around the country.  A press release can be found at http://ncam.wgbh.org/about/news/deaf-and-hard-of-hearing-users  .
