I had a little free time, so I decided to play a little with alsa. I
copied the mic verbs from the old model to this new one and it seems
to be working fine. Here is the patch for that

+/* Front Mic: set to PIN_IN (empty by default) */
+/* Unselect Front Mic by default in input mixer 3 */
 /* Enable unsolicited event for HP jack */
 /* Enable speaker output */

Now, the only 'broken' thing is jack sensing, it just mutes front, but
not LFE. I guess this is an easy to fix issue.
