Comment (by robe):

 Paul,
 Sorry about that.  I had mistakenly thought they were the same issue since
 they were generating the same error message.  The M x M case works now and
 so does the POINT, POINT.

 So just this first one I started with is inconsistent with geometry
 ST_Distance and ST_DWithin behavior.

 {{{
 SELECT ST_Distance(
                 ST_GeographyFromText('SRID=4326;MULTIPOLYGONM(((0 0 2,10 0
 1,10 10 -2,0 10 -5,0 0 -5),(5 5 6,7 5 6,7 7 6,5 7 10,5 5 -2)))'),
                 ST_GeomFromEWKT('SRID=4326;POLYGON((-8 50 2,52 -12 2,-10
 50 2,-8 50 2))'));
 }}}
