the evdev rules file is combined from the base* as well (look at the
Makefile.am). So for the +aliases to disappear you need to add it to
base.l_k.part.

that's the only thing I can spot immediately. I take it the rules file is
composed correctly and the resulting files in /usr/share/X11/xkb (or
whatever prefix) look alright?
