Hehe, ok.. but in the meantime I started coding a bonding driver.  I hope
I will finish it as it isn't too tricky for the bare bones approach.  It
will only support instructions and will be pretty minimalistic.

The only issue I have is ranges.  If the two boards have different range
sets one has to code his/her user app such that acquisition using
instructions is very careful about range settings on a per-channel
basis...
