Xmodmap & sound keys.

[Edward Jabbour <edjabr@gmail.com>]

As on many laps, this machine has keys for mute, up and down.  I have 
the proper keycodes in ~/.Xmodmap, but I can't get them to work at all.  I 
ran the verbose option and got:

[Thu Jul 16] edj:~$ xmodmap -verbose .Xmodmap
! .Xmodmap:
! 1:  keycode 174 = XF86AudioLowerVolume
        keycode 0xae = XF86AudioLowerVolume
! 2:  keycode 176 = XF86AudioRaiseVolume
        keycode 0xb0 = XF86AudioRaiseVolume
! 3:  keycode 160 = XF86AudioMute
        keycode 0xa0 = XF86AudioMute
!
! executing work queue
!
        keycode 0xae = XF86AudioLowerVolume
        keycode 0xb0 = XF86AudioRaiseVolume
        keycode 0xa0 = XF86AudioMute

If anyone sees anything I've missed here, I'm all ears.
