They're not quite identical, but extremely close. Basically, Mac OS X is Darwin + proprietary bits (Quartz, Carbon, Cocoa, QuickTime, various encumbered drivers, etc.). More detail is available at <http://www.macdevcenter.com/pub/a/mac/2001/12/21/darwin.html>; ("A Brief Review of the State of Darwin") and <http://developer.apple.com/darwin/projects/darwin/faq.html>; (Q2). For the patch, it should be "Mac OS X", not "MacOS X".
