I've spent all evening trying to rig this silly leg.

I'm sure you can all point out a million ways Maya will refuse to play nice with my setup. I've used omni joints at the hip and the ankle, but the knee consists of a normal bendy bit for Z-rotation and a gear for Y-rotation, so it consists of two joints. The knee should be bending backward (toward the locator below).
The IK setup refuses to rotate the correct way at the knee. I set the degrees of freedom and limited the rotation so it can't go "forward". Instead of going backward, the IK setup just solves without rotating that joint.
When I try to add a pole vector to point it in the right direction, the bones just rotate in all crazy directions. I'm under the impression that this is because my setup is not the usual linear three-joint human leg.
Here is the Maya file: http://alientoaster.com/misc/hosted/mech_partial.mb
It seems like it should be such an easy thing to do without any skin weighting or toe controls like a human character... I've done simple rigs in the past, but this is my first time doing something that isn't a standard biped. I would really appreciate any help on this.
Thanks!
