I went through the cus-load lists with a bit of a script and came up
with the following.  reftex was another I'd noticed before, but it
seems to have got better on its own (or maybe I was on the 21.3 code).

        * eshell/em-alias.el, eshell/em-dirs.el, eshell/em-hist.el,
        eshell/em-unix.el: Add "(require 'eshell)", to get necessary features
        when M-x customize-group loads modules before the main eshell.el.

I guess this makes some circular require's, but with the provide's are
at the top of each file it seems to work.

The esh-groups.el scheme confused me a bit.  (esh-module.el greps the
em-*.el modules for defgroups and generates esh-groups.el, to make the
group definitions available before the modules are loaded.)  I
wondered if cus-load made that redundant.  It seems to be harmless at
least.
