You need to check - the codes/numbers are used in calculations... "proj4

dm 1/10 Decimeter
so that looks good :)

If you added it to /usr/share/proj/epsg, you need to use "epsg" as a prefix
(eg. cs2cs +init=epsg:27701 +to +...). In Postgis it only cares about the
"srid" column and the "proj4text" column in spatial_ref_sys, so it's easier
to make it work.
