Happy Hacking + Emacs keybindings have changed in the last week

[Kirk Strauser <kirk@strauser.com>]

I use a Happy Hacking Lite keyboard with my Debian/sid system.  In the last
week, Emacs 21 quit responding to the left and right diamond keys as meta
and started treating them as super.  From my ~/.Xmodmap, which hasn't
changed in over two years:

    keycode 131 = Meta_L
    keycode 129 = Meta_R

I have not touched a config file on my system recently, although I've
dist-upgrade'd several times recently.  Anyone know of any changes that
would have caused this to happen, and/or how to get my old Emacs bindings
back?
