Ian just pointed out that there's some code in rdesktop to do just
that.  xkeymap.c contains stuff to pull the keymap out of the X
server, parse it up, and then do keysym->scancode translation.  Of
course, choosing a suitable keymap isn't entirely trivial, since the
server can't see what keymap the client's using.
