Maybe `cl-powerset', to be added to cl-seq.el.

Not sure about shift.  It's used to toggle the layout of the keypad
at the system level.  Also `shift-select-mode' comes into play.
So without adding `shift' to these remappings, when e.g.
`kp-7' self-inserts `7', `S-kp-7' selects the region
to the beginning of the line.

An alternative is to do as suggested in the comments:

;; X11R6 distinguishes these keys from the non-kp keys.
;; Make them behave like the non-kp keys unless otherwise bound.
;; FIXME: rather than list such mappings for every modifier-combination,
;;   we should come up with a way to do it generically, something like
;;   (define-key function-key-map [*-kp-home] [*-home])

I guess `*' should be a symbol like `shift', so it would be possible
also use this notation:

(define-key function-key-map [(* kp-home)] [(* home)])
