I could post my file as well, if that would help. I'm running 5.1 Pro. It's kinda large, though.
> One thing you can do is to bias which way the direction of bend is occuring by setting one direction to say +45 and the other to -90. It would then favor movement in the larger range of motion axis.
Favor, but not restrict? Do you have a feel for how it would decide to allow movement in the smaller range so that one can use that knowledge to predict what the solver will do and animate with that in mind?
I've gotten the thing to sort of do what I want by setting keys for one or two joints in a chain. This forces the solver to bend in a certain direction, but that doesn't look smooth or good and introduces similar overhead to keyframing all the joints.

Sadly, yes. That was the straw that broke the camel's back. I had caved in to all the other issues I didn't understand how to work around, but when it wouldn't even render what I animated I realized I was not in control and needed to understand...something... in order to at least be able to render what I scrub.

Yup.
