I don't know if this was possible 5 years ago, anyway, you can do

    (add-to-list 'ido-read-file-name-non-ido 'dired-create-directory)

By itself this only works for commands that don't use Ido completion unless `ido-everywhere` is enabled.
I think commands that use Ido even when `ido-everywhere` is turned off do so because Ido remaps their key bindings to the `ido-` version of the original command. In that case you have to disable Ido completion for the original command by adding it to the `ido-read-file-name-non-ido` list and undo Ido's remapping.
For example, disabling Ido for `C-x w` requires

    (ido-mode) ; The unmapping must be done after Ido is initialized.
    (add-to-list 'ido-read-file-name-non-ido 'write-file)
    (define-key (cdr ido-minor-mode-map-entry) [remap write-file] nil)
