Oh Cool! I happen to be unlucky enough to have such a setup. Just for fun I copied my /usr/local (bad idea, too big) to my fat32 partition as provided by the instructions far below. I took a quick look around the file structure and then immediately unmounted it, and gave it an fsck.

Well, I figure that is enough info for now if anyone wants me to do more testing just email me back. I would like to point out though the rest of my directories on the fat32 partition look to be unaffected... Cheers!
