 Well,  I  had  meant not the xkbcomp complexicity (well, in fact
for me the setxkbmap is more difficult to understand as  it  adds
some  levels  of  indirection) -- but rather the result of chang-
ing repeat via keymap with some key combination.

 In  fact  no, xset changes repeat rate via xkb (there is no such
a control in core), so it is (optionally, but almost universally)
compiled with xkb support.

 OK, will try sometime in the future.
