I miss this feature as well! In another ticket ([http://trac.openstreetmap.org/ticket/1805 #1805]) the issue was solved for plain coordinates.

Coordinate formats I'd like to have parsed are:

Normal GPS Coordinates (WGS84 Datum)[[BR]]
Decimal 12.3456 12.345 [[BR]]
DDD MM.MMM N 12 04.567 E 012 34.567[[BR]]
DDD MM SS.SSS N 12 3' 45.678" E 12 34' 05.678"

with support of + and - for the NSEW and common separators like space, comma, semicolon.

UTM (WGS84 Datum)[[BR]]
33U E 345678 N 5671234

This could be done in .js before it hits the server (matching a couple regexes), or in the the /geocoder/search_geonames endpoint in the railsport.
