It's not supported.

There is no end user oriented list of supported projections, GeoServer
talks EPSG codes which
is one step above projections (that is, full coordinate reference system
definitions).

The math needs to be added, and then a WKT definition need to be added to
the GeoServer
user coordinate reference systems (unless the official EPSG database has
anything in Miller
Cylindrical, but I doubt it, it's notorourly weak when it comes to global
projections).

The math needs to be added back in the GeoTools library, in this package
(which btw could
be seen as a list of supported projections):
http://svn.osgeo.org/geotools/trunk/modules/library/referencing/src/main/java/org/geotools/referencing/operation/projection/

and then a test needs to be developed to double check it against an
external source and
finally a patch needs to be posted on jira.codehaus.org for integration in
the library.

You can do it yourself or look into commercial support to have someone
develop it
for your

Cheers
