See http://developer.apple.com/mac/library/releasenotes/Darwin/RN-KernelExtensions/index.html#//apple_ref/doc/uid/TP40001023-CH1-DontLinkElementID_11 for instructions.  If kernel_task is listed as Intel (64 bit) in Activity Monitor, you're running the 64 bit kernel.  It's a waste of time for most people, in my opinion; I can still run 64 bit apps on 10.5 and 10.6 without the 64 bit kernel, and that's what I need.
