I'm not sure I completely understand what you are saying above, but the
problem was not in ogr2ogr, but in v.in.ogr which automatically creates a cat
column as well which then conflicts with any existing column named "cat" in
the .dbf file.

There might be a way around this in v.in.ogr which I haven't grasped yet.
