So I take it the apps you want to run reside on freeze but
you want them displayed in the X server on boneless.

Depending on your ssh config, you may want to run 
  ssh -X -l nutzer freeze
(The -X tells ssh to set up DISPLAY and forward any X apps
back through the ssh tunnel- some ssh installs do that by
default - make sure freeze's sshd_config is set up to allow
port forwarding too).  In this config you don't need to run 
xhost at all or bother with setting up DISPLAY.

If you really want to do your X without tunneling through
ssh, you need to run xhost +freeze in an xterm on the *laptop*.  
This tells the X display to allow apps from freeze to
display on boneless without the normal magic cookie authentication.
This is considered much less secure than ssh, but for a plip
connection to a laptop with no other networking there's not
much of an issue there.
