That makes sense, and your description highlighted a key bit I was missing
in the wiki for the board.

I had (wrongly) assumed that the lircd.conf applied to the remote, not a
combination of remote and board. I had a config that worked for one card
and wrongly assumed that since it was the same remote, it would transfer
directly over to the other board. I had already sorted out the eventX
device etc, but was using the wrong config file.

I now have a working remote, so thanks for that!
