So this may be the "wrong" answer, but it works
really well for me. I'm using Debian, X11 and
Emacs on an x86. To map the Alt keys to Meta,
I use:

xmodmap -e "keysym Alt_L = Meta_L Alt_L"

Could someone clue me on the right place
to put this to make it exec on init? I have
"keysym Alt_L = Meta_L Alt_L" in ~/.Xmodmap,
but it doesn't autoload. After I log in I
manually execute it:
bob@debian:~$ xmodmap .Xmodmap

 Will Microsoft permit you to use your mission critical data when
 you need it?  Linux will, and you have the source to prove it.
