Is your site-lisp directory still empty? Did you get any error
messages when you tried to reinstall auctex? What does 

  M-x find-library<RET>auctex<RET> 

do? What's the value of the load-path variable (C-h v load-path<RET>)?

I'm on Ubuntu 9.04 myself, using the emacs-snapshot package. The elisp
files from auctex are installed in 

  /usr/share/emacs/site-lisp/auctex

on my machine, with byte-compiled versions in 

  /usr/share/emacs/23.0.91/site-lisp/auctex

Have you compiled emacs or did you use a Ubuntu package? 

The way it should work is that a debianized Emacs reads all files in
/etc/emacs/site-start.d and /etc/<emacs-flavor>/site-start.d. The
packages drop their initialization code here. I've got 

  /etc/emacs-snapshot/site-start.d/50auctex.el

and you should have 

  /etc/emacs22/site-start.d/50auctex.el

Is this file present? What happens if you load it with M-x load-file?
If you really like to know how packaging emacs extensions works on
Debian you should read this:

  http://www.debian.org/doc/packaging-manuals/debian-emacs-policy

You might be interested in the part where it speaks about the 
/usr/lib/emacsen-common/emacs-package-install script (written in the
perfect emacs rewrite language, btw). 

Kind regards, 

Anselm
