thought I'd post to say I got this working with Westcrips Resurrection Remix pitchblack stock rom found here:
and using the NEAK engine. Struggled at first, but I soon realised the NEAK version bundled with the above rom was 1.3, the latest 1.6 NEAK made it work 100% after an update.
Edit: seems like I was wrong. It worked almost flawlessly for a few minutes, then became more and more intermittent. Ah well, random lockscreen CRT effect FTW!
Second edit: This is using NEAK v1.6 on XXDLK7 base and a deodexed (I think) rom. Would love to get it working 100% on NEAK kernel as I find Wolfson Audio to be by far the best sound on the Note 2
