Plugin doing the right thing: http://www.vim.org/scripts/script.php?script_id=441

“This plugin searches for local vimrc files in the filesystem tree of the currently opened file. By default it searches for all ".lvimrc" files from the file's directory up to the root directory and loads them in reverse order. The filename and amount of loaded files is customizable through global variables.”
