I am not sure, but iirc there is at least an issue with internal ram
size, maybe you could compare sizes of the 2 blobs.
I remember that with 770 we couldn't be as aggressive as with n800
because the fw would have taken up too much memory.

So i wouldn't be surprised if they n800 module wouldn't work on 770 ...
