I think that there's something missing for Emacs. As I've said, the
xterm.el file contains only:
(define-key map "\eOj" [kp-multiply])
(define-key map "\eOk" [kp-add])
(define-key map "\eOl" [kp-separator])
(define-key map "\eOm" [kp-subtract])
(define-key map "\eOo" [kp-divide])
(define-key map "\eOp" [kp-0])
(define-key map "\eOq" [kp-1])
(define-key map "\eOr" [kp-2])
(define-key map "\eOs" [kp-3])
(define-key map "\eOt" [kp-4])
(define-key map "\eOu" [kp-5])
(define-key map "\eOv" [kp-6])
(define-key map "\eOw" [kp-7])
(define-key map "\eOx" [kp-8])
(define-key map "\eOy" [kp-9])
Why nothing for [kp-equal]?

But my point is that the case for "O" and "X" matters. For instance,
M-O A moves the cursor up, but M-O a is undefined.
