It's probably not the whole answer because when I tried it out in mapsource, the exit name wasn't mentioned in the routing instructions.
It would be good if someone tried out routing via a motorway exit using a map generated with the above addition to points to see if a real GPS mentions the exit by name or not - I suspect it won't but maybe we'll be lucky.
Tried that on my Nuvi 250 (first with 0x2000 and then 0x2700) neither of those seem to have any effect. However, changing highway=motorway_link from 0x01 to 0x09 (meaning "Highway exits and connecting ramps" (according to http://www.malsingmaps.com/wiki/index.php/POI_and_Road_object_Reference)) triggers some additional instructions (e.g. keep right onto <motorway-name/ref>). - Michel
