Comment(by strk):

 With r13298 (trunk/2.2.0dev) I've committed a change to
 postgis_typmod_dims to return NULL.
 The geometry_columns output is still unchanged to gather more opinions
 first.

 The changeset includes an update to the geometry_column view definition to
 not assume a return of 2 from postgis_typmod means unconstrained, which
 sounds like a bug on itself (it works because the query later assumes 2 if
 the column is not constrained by checks, so it refuses first typmod
 constraint, fails to find check-based constraints and defaults to 2).
