Nigel, to say the truth SRID=-1 *special* handling is not used yet,
but has been proposed. It won't be in PostGIS-1.0.0 though. The
dimension -1 will probably be implemented at the same time.
About mapserver you shouldn't have any problem as all geometries are
converted to 2d before parsing anyway, I don't think it uses
the 'dimension' field of geometry_columns at all.
