I think some kind of hierarchical/combining approach would work.  Most
keyboards would support almost everything, which would be in the
default keymap, then there's a small change for keyboards that can't
detect Control, for keyboards that don't support a separate Field+
key, and then the user's customisations on top of that.

The same thing could apply to the display - some displays don't
support underlining, they're either colour or black-and white, some
only have 24 rows, some will fit 132x27, some can be resized to that,
some support a mouse, etc.

The only sticky bit might be:

} Except as contained in this notice, the name of The Open Group shall
} not be used in advertising or otherwise to promote the sale, use or
} other dealings in this Software without prior written authorization
} from The Open Group.

which could contravene section 6 of the GPL by imposing additional
restrictions on the distributor.  This might fall under section 0 of
the GPL, though:

} Activities other than copying, distribution and modification are not
} covered by this License; they are outside its scope.

In practice, I haven't seen anyone that worried about combining GPL
and X11 licensed software.
