 layouts = []
 overrideSettings = false
 options = []
 model = 

If it matters, I also have this in .xsession:

xmodmap - << END
keycode 26 = e E EuroSign
keycode 54 = c C cent
keycode 59  = comma        less       guillemotleft
keycode 60  = period       greater    guillemotright
keycode 34  = bracketleft  braceleft  leftdoublequotemark
keycode 35  = bracketright braceright rightdoublequotemark
keycode 108 = Mode_switch
keycode 133 = dead_grave   dead_acute
keycode 135 = Multi_key
END

(I welcome ideas about how to do the same with xkb, BTW.)

Yes.

I'd rather not install the whole gnome toolchain, but if you have an
unstripped i386 library around I can copy it over the system one.
