Included below is my .xmodmaprc file:

remove Mod1    = Alt_L

keycode 0x3D =  Down
keycode 0x3E =  Up

add    Mod1    = Meta_L
----<included text ends above this line>----

and I just put the following line in my .xinitrc:

xmodmap $HOME/.xmodmaprc

That's it.  Removal and addition of Mod1 means I use the command key
instead of the option key for Mod1 modifier.

You'll need to modify the original source from the X consortium.  If I
were you, I'd wait until the diffs are released by Allen (uh, I *am*
waiting, actually).
