Are there any efforts in process to make POV take advantage of multiple CPUs
in a box ?

  Which system we are talking about?

  Please note that povray is a cross-platform program.

good point ... unfortunatly all the threading issues are generally OS
specific.

I was talking about Windows / NT system

Making a multi-processor POV would not only require figuring out some 
way to implement threads in a platform-independant way, but all of the 
problems with global variables, caches, and other shared data would have 
to be sorted out. Basically, a complete rewrite and redesign is 
necessary.
POV-Ray 4.0, which will be a rewrite in C++, will solve some of these 
problems. While it itself might not be multiprocessor enabled, it will 
be a step in the right direction. This *is* being discussed, but right 
now, the POV Team is concentrating their free time on getting 3.5 
released.

Isn't this in your VFAQ?

  The VFAQ answers why it is difficult to make a multithreaded povray. It
doesn't tell if there's any project going on doing it (mainly for two
reasons: 1) I don't know any specifics and 2) the info will probably get
outdated in a near future).
