Unfortunately you don't mention with which Gnus version you tested it.
In the current trunk and in the stable branch (v5-10), Katsumi Yamaoka
recently improved handling of charsets for XEmacs:

--8<---------------cut here---------------start------------->8---
2004-11-02  Katsumi Yamaoka  <yamaoka@jpl.org>
[...]
        * mm-util.el (mm-mime-mule-charset-alist): Add the windows-1251
        entry.  From Ilya N. Golubev <gin@mo.msk.ru>.
        (mm-enrich-utf-8-by-mule-ucs): New function run when Mule-UCS is
        loaded under XEmacs.
        (): Don't make duplicated entries in mm-mime-mule-charset-alist.

        * mm-util.el (mm-coding-system-p): Return a coding-system.
        (mm-mime-mule-charset-alist): Use shift_jis instead of
        iso-2022-jp-2 for the katakana-jisx0201 mule charset; add new
        entries for the mime charsets iso-2022-jp-3 and shift_jis.
        (mm-coding-system-priorities): Use shift_jis and iso-8859-1
        instead of japanese-shift-jis and iso-latin-1 respectively in
        order to share the default value with both Emacs and XEmacs-mule.
        (mm-mule-charset-to-mime-charset): Make
        mm-coding-system-priorities effective.
        (mm-sort-coding-systems-predicate): Canonicalize coding-systems
        while predicating of candidates upon the priorities.

Please write to the Gnus mailing list (ding@gnus.org) which is also
available as a newsgroup (nntp://news.gmane.org/gmane.emacs.gnus.general).

Could you please check if (or which parts of) your patch are needed in
a current Gnus CVS version (trunk or stable branch (v5-10) won't make
much difference, I think).

If the remaining addition to `mm-find-mime-charset-region' is quite
long (as your current patch) I think this part should be separated
into a new helper function so that `mm-find-mime-charset-region'
remains readable.

If your patch is more than a "tiny change" (approximately 15 line of
new code, IIRC), we need a copyright assignment.

Bye, Reiner.
