Sorry, it turns out that's wrong: the gpsbabel developers recommend not
using garmin_gps because apparently it often doesn't work.  Instead
they recommend using gpsbabel's 'garmin' input/output format.  It
interfaces to the device using libusb - which, fortunately for us runs
on FreeBSD! I've just successfully read back GPS data into a GPX file
using gpsbabel on FreeBSD 8-CURRENT and the 'usb2' usb stack. 

I don't know if it'll work with the usb stack that's in shipping
version of FreeBSD though, and even with the new stack I had to make a
change to libgpsusb.c in gpsbabel to get it working.
