Did you do something special?  Because in my emacs, A-x doesn't invoke
execut-extended-command.  I have to type M-x to get that.

You can find interesting keysyms in /usr/include/X11/keysymdef.h
You can use xmodmap to bind keycodes to the keysyms you want.
And you can use global-set-key to bind keysyms to the functions you want.

To replace the keysym Alt_L and Alt_R by Execute you can evaluate:

(shell-command "for code in $(xmodmap -pke|awk '/= Alt/{print $2}') ; do
xmodmap -e 'keycode 133 = Execute' ; done")

There is already a binding from the Execute keysym to
execute-extended-command in emacs-version "24.2.1"
If not, you can bind it with:

(global-set-key (kbd "<Execute>") 'execute-extended-command)
