All you really need to do is convert the DEM into TGA using one of the
several programs capable of doing so.
I've used Wilbur:

The POV Links has what looks like a real good one:
http://www.monumental.com/rshorne/3dem.html
And a web page worth looking at (mentions POV-Ray) is:

Then all you have to do is use the image as a height_field.
