Was I wrong?
It looks like CONFIG_VIDEO_V4L1_COMPAT=y should be sufficient, except for radio drivers that only support v4l1. We know that isn't the case for your driver, since it works with the "radio" program. Probably, fmtools needs support for v4l2. I will add this to my to-do list. (My to-do is quite long, so I cannot make any promises about when I will get around to it.)
