Fixed it. It wasn't that. For the archives, I verified that by setting the clear color of the first camera to red, and the second camera to blue. The screen was red.
My problem was that when I set the projection matrix, I tried to just change the near and far clip planes. You can't do that if you are setting by frustum, since the variables are not independent. I'm sure there are calls to do this, but I was simply changing the n&f values, which was bad. Thanks for the help.

I've written lots on the mailing list over the last year, so have a look at the archives.
