We did such a thing using a modified Python script, processing
Tiger/Line files into Shapefiles for our project. The original
script we started with was "tigerpoly.py" from GDAL/OGR, and our
modified version is "xastir/scripts/Xastir_tigerpoly.py".
So yes, it's possible, and there are a couple of pointers for you!
