You should definitely pass the following environment variables without
asking, since GNOME applications won’t work without them:
        DISPLAY
        XAUTHORITY
        ORBIT_SOCKETDIR
        DBUS_SESSION_BUS_ADDRESS

The following shouldn’t hurt as well.
Terminal:
        TERM
        COLORTERM
XSMP support (probably doesn’t work in a chroot):
        SESSION_MANAGER
gnome-keyring (only the SSH stuff works across the lenny→squeeze
upgrade):
        SSH_AGENT_PID
        SSH_AUTH_SOCK
        GNOME_KEYRING_CONTROL
        GNOME_KEYRING_PID
seahorse:
        GPG_AGENT_INFO
Used by xdg-utils and debianutils scripts:
        XDG_SESSION_COOKIE
        DESKTOP_SESSION
        GNOME_DESKTOP_SESSION_ID
GTK+ modules to load:
        GTK_MODULES
        GTK_IM_MODULE
Language:
        LANG
        LC_*

Passing all of /var/run looks a bit dangerous to me since it could lead
some scripts in the chroot believe that a daemon is started in the
chroot. I’m not sure if that’s a real problem, but you should probably
at least print a warning somewhere.

Great!
