Mark,

I believe the OGR NTF driver supports treating a directory of 
NTF files as a single dataset.  So, dump all your address point
files into one subdirectory, and then use the subdirectory name
as the input for ogr2ogr.  It should create one merged Mapinfo
dataset. 

BTW, I'm not too sure what version of ogr2ogr you are using, but
a fairly recent one is pre-built as part of the FWTools kit at:
