I can't help with Geomorph as I've never used it.

There are quite a few different approaches. I did a quick Google, but didn't 
spot any tutorials, though I had a feeling that Christoph Hormann had done a 
good tutorial on this sort of thing a few years back.

There are some utilities that can generate bumpy terrains as height_fields. 
You can generate height fields using POV-Ray textures. There's a recent 
addition to the Object Collection at 
http://lib.povray.org/searchcollection/index2.php?objectName=TextureGen&version=1.0&contributorTag=worldbuilder

that illustrates how to generate height_fields that seamlessly tile 
horizontally. When I saw it I added a little writeup on it here: 
http://lib.povray.org/collection/texturegen/worldbuilder%201.0/texturegen.html. 
Although it looks like it was primarily intended for generating planets and 
asteroids, you could use a crackle pattern with that scene file to generate 
a heightfield with a cracked surface.

If you don't need actual cracks that you can 'look' into, you may be able to 
simulate them using a highly accentuated crackle pattern as a surface 
normal.

Otherwise IsoSurfaces and meshes can be used to generate terrain. I'm 
currently doing some work with the elevation data published by the US 
Geological Survey at http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/Eurasia/ 
which contains binary data for every type of landscape on earth. I've 
converted the UK data into mesh2 objects. If that sort of thing interests 
you I'd be happy to share my scripts or convert a small section of data for 
you.
