I found a post here from 07 saying something about removing it a long time ago, but it got no answers.

it's the bits you found in /proc; there are no (longer?)
any special real time processes; any process can become
real time by setting up deadlines at any point.

/dev/realtime isn't needed any more.

unfortunately, I'm not aware of any programs using it.

(that may be a good question for the list: where was the
real time scheduler used, and does any code using it
survive?)
