Hmm the n810 isn't happy for me in many ways:
    a) It boots up to a desktop like thing with a couple of colourful
       characters and a few icons but I can't interact with it at all.
    b) Migration with current upstream fails with a migration format error after
       the sd card on load - it goes if I revert 
dd26eb43337adf53d22b3fda3591e3837bc08b8c
       - my suspicion is that wpgrps_size isn't being initialised by the time
       of the load; but I've not dug into it.
    c) Even if I revert the commit in (b) reloading from a migration image
       gets me a blank white screen in paused state.

So I think that model is pretty broken anyway.
