This is problematic, as I've noticed that the tmc0351 and 2 from a MTA1179 board and the tmc0351 and 2 from a 1980 board do not have the same contents, but do have the same part numbers. Same with the TMC0271 from the MTA1179 (which has the module 'bug') and the one from the 1980 board (which doesn't).
(maybe at some future date we can try to dump them? I think it may be possible to do using probes on the 4 data lines and otherwise through the edge connector itself)
