There's a gazillion POI Garmin types available, but only a couple of  
hundred are distinct icons - so you get a lot of repetition.  As far  
as I know, you can use any POI type code you like, combine it with the  
corresponding style file entry to assign it to a given OSM tag, and  
then use a TYP file to give it the symbol you want.

FWIW, I'm (slowly) putting together a spreadsheet with each type code  
and the corresponding default symbol (i.e. how it appears on the GPSr  
unit when you're not using a TYP file).  To do this I wrote a little  
app in c that outputs an OSM file containing a regular grid of POIs  
with an associated points style file that assigns a unique type code  
to each node.  It can generate an arbitrarily large grid of POIS.  At  
the moment I'm working through the first 10,000... :)
