DMU Authentication with Pub Keys after 4.3 OTA (10.key, 41.key, etc)

Since 4.3 it seems that DMU public key authentication is no longer working even when the folder is added manually. The phone instead uses username/password + HA/AAA. Bad deal for me as my phone pulls correct keys but not the passwords. I don't know if they are backwards or where they stop/end as the as the length fields are missing. Its as if *228 is combining and writing different NV items together.

My other phone, a GS2 I can put almost anything for the passwords and since 10.key is correct along with HA/AAA I get 3g data. The S3 fails AAA, CHAP & PPP, Is there any way to enable use of DMU pubs after 4.3?
