Are you sure you mean Geofabrik, I didn't think they provided any maps 
in Garmin format?

Anyway, this is a known issue with Mkgmap, the software used for 
generating most Garmin format OSM maps. The Garmin img format is not 
fully understood, so its not known how to make the address search work 
properly. It seems it works on some Garmin devices but not others. See 
http://wiki.openstreetmap.org/wiki/Mkgmap/known_issues

I don't know if this has been improved in more recent versions of 
Mkgmap. I see Mkgmap now has an option "--index" which creates MDR and 
MDX index files, for address search in Mapsource, but I don't know if 
you can transfer these to the GPS device.
There is also the option for "--road-name-pois" which will create a POI 
for each road, which you can then search for. The problem with this is 
it creates lots of ugly dots everywhere, and it clutters up the POI 
search with road names.
You could try generating some maps with these options and see if they help.
