You're looking for the local device class definition 
in /etc/bluetooth/hcid.conf.  It's a bitfield.  Googleing for hcid.conf gives 
me one of my favourite documentation sites, die.net: 

http://linux.die.net/man/5/hcid.conf

About halfway down you can see what the device class is composed of and what 
each bit means.

I imagine you want to use rfcomm; it has a 'listen' command that would allow 
you to attach your own utility (which spits NMEA sentences out to stdout) to 
an rfcomm channel.

You may also have to configure an SDP record to "advertise" the rfcomm port to 
the phone you're testing with.  "sdptool add" would probably be what you want 
here.

I'm not an expert either, but us newbies have to stick together and pull 
ourselves out of this muck.  :-)
