should work since vim 6.0;
may be modelines are disabled per default for security concerns?
http://vimdoc.sourceforge.net/htmldoc/options.html#'modeline'

you can figure if modelines are enabled and if the area is big enough, by
checking the settings: [ESC]:set

or try [ESC]:help modelines.
and if approbiate review your .vimrc/.exrc

modeline <boolean>
modelines <no_of_lines to check>

defaults to 5, if your comment before (at the beginning of the file) or
after (at the end of the file) is to
big no modeline gets loaded.
