So, 

was changed to present linux keycode maps for installation instead of
ADB keycode maps (which used to be the norm for powerpc kernels). The
ADB maps are no longer officially supported.

and

support for ADB keycodes is unable to use ADB keymaps. Linux keycodes

Sounds like a good idea for boot-floppies, maybe a commented out one
upstream, since it could break existing setups. 'Course, they
shouldn't be using a default installation on an upgrade...
