These files can be used to change server settings, e.g.
 $ xkbcomp server-0.xkb-4.3.0.dfsg.1-6 :0
tells my server to use your settings.  These files are expanded versions
of those found under /etc/X11/xkb, which means that I can test the exact
same settings as yours (given that I also have a PC keyboard).
And the syntax is the same as XKB data files, so their documentation
is...quite harsh.  Here are some bits:
  /usr/share/doc/xserver-xfree86/README.XKB-Config.gz
  /usr/share/doc/xserver-xfree86/README.XKB-Enhancing.gz
  http://www.tsu.ru/~pascal/en/xkb/
  http://www.charvolant.org/~doug/xkb/

When loading server-0.xkb-4.3.0.dfsg.1-6, xev output seems right, as you
can see below, so I tag this bug as being unreproducible.  I have no
more idea at the moment to solve this bug, sorry.
