I've got things set up the other way around.  I use right alt as Mod3
and left alt as an ordinary alt key.  Here's my .xmodmaprc file in case
anyone's interested:

$ cat ~/.xmodmaprc
! Change Right-Alt into Mod3 for use with xmonad
remove Mod1 = Alt_R
add    Mod3 = Alt_R

Took me a while to figure out that I had to remove Mod1 before adding
Mod3 to get it to work properly.
