Hrm, I now realise that this doesn't actually do what I'd expect - it
only writes out the provided data, there's no inclusion of the register
address.  I'd been mislead by the fact that it is taking in the register
address as an argument and an overly hasty review it seems.  That's a
little too raw for me, we should be prefixing the data with the base
register address.
