The point it that it makes no sense to add an MACH_ID to the database
for a board that probably will never run Linux.

This approach was rejected in 2009 when I initially send patches for
this board. But I would like to go that way (adding a comment so that it
is clear what is going on) So, I expect that this is OK and I send a
patch then when time permits.
