After looking at this, I think we actually want to be calling SN07(20C)
on these machines - they implement an 0x127 function in the C function
slot which also calls GECR. I suspect that this corresponds to the
larger number of programmable buttons, so should be added to another
table. Something like the following - some amount of tidying up
required. That would avoid needing to add a multilevel setup.
Interestingly, the recent SRs also appear to implement the 0x124 rfill
method, but at SN07(4) rather than SN07(3). This leaves me pretty happy
that I've got the right idea about how this all works now :)
