Description of problem:
    When numlock is on, X server sends key press/release events with
    inconsistent keysyms.  For example, press and release "4" on
    keypad, and one gets keypress with KP_4, and keyrelease with
    KP_Left (wrong, should be KP_4).  Same with Shift key on and Num
    Lock on: one gets KP_Left (down) and KP_4 (up; wrong, should be
    KP_Left).

Version-Release number of selected component (if applicable):
    xorg-x11-server-Xorg-1.12.0-5.fc17.x86_64

How reproducible:
    always

Steps to Reproduce:
    1. Run the keysym.tk in the "Additional Info" section below.
       Any X app showing keysym should do; I use TK because it's
       easy to set up.
    2. press and release Num Lock until Num Lock LED is on.
    3. press and release "4" on keypad.
    4. press and hold Shift key, the press and release "4" on keypad.
 
Actual results:
    sees keypress   with keysym KP_4    (good)
    and  keyrelease with keysym KP_Left (bad)

Expected results:
    the keyrelease event should have keysym KP_4 as well.

Additional info:
    1. keysym.tk: a simple TK script to show keysyms
      #!/usr/bin/wish
        message .msg -width 8c -justify left  -font "-adobe-courier-*-24-240-75-75-m-150-*" -text "this is a test"
        bind all <Any-KeyPress>   { puts "keyPress   the keysym is %K" }
        bind all <Any-KeyRelease> { puts "keyrelease the keysym is %K" }
        pack .msg

    2. The Xorg server on Fedora 14
           xorg-x11-server-Xorg-1.9.5-2.fc14.i686
       is working properly: same correct keysym for key down/up event.
       This issue was probably introduced between F14 and F16.
