Do you mean after (require 'evil) and before (evil-mode 1)?  That
didn't work unfortunately.

Specifically, I have key bindings

(define-key evil-normal-state-map "o" nil)
(define-key evil-normal-state-map "O" nil)
(define-key evil-motion-state-map "o" 'next-buffer)
(define-key evil-motion-state-map "O" 'previous-buffer)

Which I want to work in all buffers, including buffer-menu.
