Thanks for that info, Steve. However I still cannot get it to work.

When I run make-kpkg with the --arch parameter, it seems to always try
to use a cross-compiler - i486-linux-gnu-gcc (or something like that -
I've forgotten exactly and its scrolled off the screen now). This
happens whether I prefix make-kpkg with "setarch i386" or "linux32" or
not.

If I supply the argument "--cross-compiler -" it uses the correct
compiler but always builds a package for the host arch not the target
arch.

I got around it by hacking make-kpkg itself. It seems if you specify
--arch, it will build a deb for the target arch, but only if you dont
specify "--cross-compiler -". I remove the check for that, and now it
works fine.
