Solution to 64bit Kernel on Late-2008 MacBooks

Jake pointed me to this excellent guide to permanently enabling 64bit kernel booting on the Late-2008 MacBooks and other officially unsupported Macs. If you scroll down to comment #21 on the guide, Jake offers a tip for other Late-2008 MacBook folks about how to get the fix to work after a reboot.

It goes without saying that if you follow the guide linked above, you do so at your own risk.
