From /usr/include/linux/input.h

We maintain it here since it is such a painful mess.

Here is a little script to make it easier:

#!/usr/bin/perl
while (<>) {
	$_ =~ s/-XK_/XK_/;
	next unless /^XK_/;
	chomp;
	if (/^(\S+)(\s+)(\S+)/) {
		$a = $1;
		$t = $2;
		$b = $3;
		print "\tcase $a:${t}return $b;\n";
		if ($a =~ /XK_[a-z]$/) {
			$a = uc($a);
			print "\tcase $a:${t}return $b;\n";
		}
	}
}

This only handles US kbd, we would need a kbd database in general...
Ugh: parse dumpkeys(1) or -fookeys /usr/share/keymaps/i386/qwerty/dk.kmap.gz
