I'm afraid I've been out of the loop for the past month so am unaware of which version that is, if it's the latest, you should have everything under "/usr/libexec/sfdroid/", can you see if you have init.sfdroid.rc on your device?

I believe TheRealJohnGalt could answer these questions but at the time of writing, he should be sleeping.

UPDATE: It seems the update I'm talking about that changes the Android System folder location hasn't been rolled out yet, and still in development, so once that comes, then try this approach. I might even create a patched supersu zip for you to flash, if it works.
