I found that needing the remote to tune to a frequency rather than either needing to use a preset or letting the tuner decide what was strong enough to be a station annoying, and figured the right answer was to allow a selectable mode (maybe the default mode, probably not) on the knob when tuner is selected to be "single-step up or down". I set about figuring out how I might need to patch Hijack to accomplish this, and noticed the tuner device driver has been removed.
I don't see another way to set frequencies, and it looks like the tuner device driver didn't support usefully getting the current frequency anyhow (making single-stepping rather hard), but I wanted to make sure I didn't miss something.
I'm hoping one of you will tell me I'm crazy, because I'd prefer being crazy to being SOL
