Yep, but it does it without your having to use xmodmap.  Because xmodmap 
adds a lot more places for things to go wrong, this makes it easier to 
configure.

Same as you did:

None XF86AudioRaiseVolume :ExecCommand volume.sh up
None XF86AudioLowerVolume :ExecCommand volume.sh down

etc.  To figure out which keys your new X definition supports, just 
search the 'net for the name of the X keyboard model (i.e. "itouch" or 
"microsoftmult" or ...) or you can get it yourself by watching the 
keystrokes with an appropriate program.
