What would it take to duplicate the way in mkgmap, as highway=cycleway,
oneway=-1?  This could of course be done relatively easily by preprocessing
the OSM data before feeding it to mkgmap, but I would consider it an ugly
workaround.

Nitpicking: I thought that bicycles are human powered vehicles. :-)

BTW, are there any non-OSM Garmin maps that feature routeable cycleways?
Such a map could be useful for reverse engineering.  (I have only used
OSM on my Edge 705, and I read that a commercial map of Finland lacks
routing data for cycleways, even though some ways are visible on the
screen.)
