I have fairly recent patches (for v4.10) here:
https://github.com/filippz/pmbootstrap/commit/600473432d8ff61ae80a7e2a198d9442fd3a6f2e
(from 0015 trough 0022 w/o 0016). Vibration was working as was audio
playback from twl5031 and tvl320dac33 together with tpa6140a2. More
details here: http://talk.maemo.org/showpost.php?p=1492590&postcount=112
I hope that you can use those patches at least to some degree.

I haven't used FM radio nor BT (wl1273), so I can't comment on that, but
they are in there but probably need some work.
