Ok thatmakes a great deal of sense. Of course the argument *could*
be made (not that I am - I am playing devil's adovate here) that unlike
other input devices which have many varied protocols, the keyboard is
a notable exception. In effect a simpel trade between ifdefs and OS
specific hooks has been made. I'm not saying its a bad thing at all,
but (and this goes to the second part of this reply below) if a choice
had to be made to keep the old stuff around it would not be the worst
decision one could make :)

That is *possibly* true. For some platforms, I am guessing that things
have worked for so long that the *need* for an active maintainer has
waned considerably, until things like this came along. However, if you
are looking for a lithmus test to see how popular/not popular a given
port is, I can't think of a better way than making their keyboards
not work *grin*
