Well, http://wiki.kraszewscy.net/Cross_DistCC shows how to do it (in Polish, 
sorry).

In short:

---8X---[ setup for COMPILER machine (AMD64) ]-------------------

1. make directory /opt/cross32/bin
2. make there a file "i686-pc-linux-gnu-wrapper" containing

  #!/bin/bash
  exec /usr/bin/x86_64-pc-linux-gnu-g${0:$[-2]} -m32 "$@"

3. make it executable
4. make soft links in that directory

 ln -s i686-pc-linux-gnu-wrapper gcc
 ln -s i686-pc-linux-gnu-wrapper g++
 ln -s i686-pc-linux-gnu-wrapper c++
 ln -s i686-pc-linux-gnu-wrapper cc
 ln -s i686-pc-linux-gnu-wrapper i686-pc-linux-gnu-gcc
 ln -s i686-pc-linux-gnu-wrapper i686-pc-linux-gnu-g++
 ln -s i686-pc-linux-gnu-wrapper i686-pc-linux-gnu-c++
 ln -s i686-pc-linux-gnu-wrapper i686-pc-linux-gnu-cc

5. copy "/etc/init.d/distccd" to "/etc/init.d/distccd32"

6. fix "/etc/init.d/distccd32" to have

       TMPDIR="${TMPDIR}" \
       PATH="/opt/cross32/bin" \
       /sbin/start-stop-daemon –start –quiet –startas ${DISTCCD_EXEC} \

7. copy "/etc/conf.d/distccd" to "/etc/conf.d/distccd32"

8. fix "/etc/conf.d/distccd" to have

	DISTCCD_OPTS="${DISTCCD_OPTS} --port 3664"

---8X---[ end of setup for COMPILER machine (AMD64) ]-------------------

Now you have two distccd daemons: 
* one at port 3632 for 32-bit distcompiling
* one at port 3664 for 64-bit distcompiling

At this point your Opterons will handle remote 32-bit compiling - you don't 
need to make any changes on P4 machine other than activating regular distcc.
