It is true that that mac os x is based on the Darwin project. However, the entire os is not open source. Aqua and its components are proprietary and does not suport x86 hardware. Linux User & Developer Magazine has a feature in the back dedicated to explaining Mac OS X called Bite of the Apple. Basically, As of now you can not run Aqua on an x86 archetecture. If I'm not mistaken, the only portion you could install would be Darwin and then you would be left without a graphical user interface. I'm not at home now but I think the issues of the mag are #39 &40. It is a UK publication and costs like $11 us. The plus is there are coverdisks with diferent distros. The last one had Xandros and Lycoris distros as coverdisks, the month prior it was Suse 9. Sorry to dash those hopes. Maybe someday.
