If you refer to the amd64 howto, it is shown how to bind chroot /home -
I'm assuming you have a chroot.


Running applications inside the chroot (e.g. OpenOffice.org)

To run an application inside the chroot you will need some parts of your
64bit system tree inside the chroot. This can be achieved with a bind
mount. In this example we will bind /tmp to the chroot for the X11
sockets which are in /tmp, and bind /home to access the home directories
from within the chroot. You may also want to mount the /proc and /sys
filesystems within the chroot. Edit your fstab and add the required

# ia32 chroot
/home           /var/chroot/sid-ia32/home none  bind            0
/tmp            /var/chroot/sid-ia32/tmp none   bind            0
proc            /var/chroot/sid-ia32/proc proc  defaults        0
