Not really.  The best way to do this is to download and unpack the
Debian emacs22 source package, e.g. with "apt-get source emacs22".
There you can find all the patches in the debian/patches subdirectory.

Could you elaborate on that?  The Debian packaged Emacsen look for site-lisp
directories both under /usr/share and under /usr/local/share.

Correct.

Snapshots of the Emacs trunk are still built weekly by Romain Francoise,
see http://emacs.orebokech.com/.  That's probably the best starting
point for building a debianized unicode-2 Emacs.
