AFAIK, to find vim-latexsuite, vim should look in /usr/share/vim/addons/, which it does not. OR vim-latexsuite should be installed in /var/lib/vim/addons/, which it is not...
Continuing this reasoning, adding the following to my .vimrc should fix it:
set runtimepath+=/usr/share/vim/addons/
Opening a .tex-file after making this modification, things now work...
(Oh, and I had vim-full installed, but vim-latexsuite still did not work for me...)
