Can't speak to the 3750, but after querying TAC about uRPF for the
3550 last November, I got this response:

  uRPF (unicast Reverse Path Forwarding) is and will most likely never be 
  supported on the cat3550. As you have seen, it can be configured but this 
  comes from the fact that this is due to the fact that the command is 
  available in the generic IOS code. But that does not mean that is is 
  supported. 

We'd love to hear different, but it doesn't appear likely.
