Alan, in Emacs, minor-mode maps override major-mode key maps.   If Home/End are bound in a minor-mode map, then they will be prioritized over your settings.  And this is indeed the case.  `osx-key-mode' (where most key bindings are made that are specific to Aquamacs) sets home and end, and it does precisely because some major modes redefine elementary navigation keys (and they shouldn't do it for UI consistency).

Now, one solution would be for you to simply bind your keys in osx-key-mode-map (see also the Aquamacs FAQ), but the better way could be to set `ns-function-modifier' to an unused modifier like `super', and bind that.  Here, the problem is that Aquamacs does not yet recognize function key combinations with arrow keys (this may be a system limitation, IIRC).

Hope that helps.
