Uhm, I'm sorry I wasn't clear enough on what I wanted (gee, I don't
think I clearly knew what I wanted).  So, here it goes:

Does your code have an interface, I mean a program interface, not a
user interface, to install/deinstall a key map on the fly?  I mean,
without having to rebuild a kernel, or even having to reboot.  I think
this is very important because then we won't have to make a "special"
kernel for everyone who wants a new key map.  And I don't like the
idea of keeping every possible key maps around in the kernel, many of
which I'll never use.  So, I think it's better to supply such an
interface (probably an ioctl() for /dev/adb) and key map definition
files for various international keyboard layouts.  And a user can
install any of those as he/she wishes, or write one if there isn't any
already written for his/her keyboard layout.

This can be done in /etc/rc.local and you can forget about it once
the system is up.  Only drawback I can think of with this scheme is
that one has to put up with the default key map until a preferred map
is manually installed when booted in the single-user mode.  But I
don't think it is too high a cost to pay for the benefit I described
above, is it?
