Maybe I wasn't clear. PAM was already emerged. I just built the new
kernel, set the rt limits as per the proaudio kernel setup page, and
it worked first time. No problems at all.
realtime-lsm is not loaded and Jack starts with realtime capability so
I guess it's working. Easy. I didn't do much of anything.
