Well, thanks to Jan Vroonhof, who pointed out that the XEmacs isearch-mode.el isn't all that different from GNU Emacs' isearch.el, I took a stab at porting this, and it wasn't very hard. Patch follows. I haven't cc'd xemacs-patches, as I'd like people to try this out, and see what they think. If everything's fine, I'll send it to xemacs-patches next week. The patch is relative to the 21.1.4 isearch-mode.el.
