Perhaps your installation is not good? I have 1.4.2 installed as well, and it seems to exist fine:

Prelude> :m Graphics.X11.Xlib.Extras
Prelude Graphics.X11.Xlib.Extras> :t setKeyEvent
setKeyEvent :: Graphics.X11.Xlib.Event.XEventPtr
               -> Graphics.X11.Types.Window
               -> Graphics.X11.Types.Window
               -> Graphics.X11.Types.Window
               -> Graphics.X11.Types.KeyMask
               -> Graphics.X11.Types.KeyCode
               -> Bool
               -> IO ()

/usr/lib/ghc-6.8.2/package.conf:
    X11-1.4.2
/home/gwern/.ghc/x86_64-linux-6.8.2/package.conf:
    X11-1.4.2

(I suppose it's possible things were changed after the version was changed to 1.4.2, but the cabal version hasn't been bumped; I'd try installing from darcs <http://darcs.haskell.org/X11> and seeing whether it changes.)
