There is no such setting. With some clever hacking on the init script, you could make android think that the sdcard is somewhere else, but I don't think anyone has done so.

(To clarify, in case I misread your question, there is a setting to put all the android boot files in one folder -- and, in fact, it is the default setting. That's the andboot folder. Just put the whole folder on your sd card, and you're good to go.

There is NOT, however, a setting to keep android applications from storing files on the sd card. My sd card is pretty cluttered due to this. Hmm... maybe I should try that. ...though I have a feeling that it'd make a lot of things not work quite right, in a really annoying way.)
