It should definitely work with r1485, because that is before the branches/mp
merge.  (I haven't been able to generate a map for a while, and it is possible
that it has changed something in the handling of relations.)

Can you download a small extract around a route in JOSM, save it to a file,
and have mkgmap process that file?  I can help you if you give me the browse
URL of the way or relation.  For example, here is a route=ferry relation
that I have successfully used for testing:
