I am not sure if it solves your problem,
but if you use POV-Ray for Windows, you
can start a rendering and then stop it.
Then you can just select a region in the
rendering window with the mouse. POV-Ray
will then render this region only.

IIRC you can also give POV-Ray command
line options to achieve the same, but I
have not done this. (So you may want to
read about it in the manual.)
