The following is an excerpt from a comment by Michael Schutte to
bug #734164:

  * The kbd init script offers several things that console-setup
    doesn't, namely the option to configure different fonts on different
    consoles, the possibility to modify the keymap through a sed script,
    the configuration of the screensaver through setterm from
    util-linux, and the startup of other console-related utilities
    shipped with kbd (vcstime, kbdrate, setleds).  I don't know if these
    features would be considered a good fit for console-setup; I suspect
    that all of them are used very rarely.
