Installing on an IBM 600X - anyone tried it?

[Mr. Ralph]

Hi folks,
  I installed FreeBSD 5.3 on an IBM 600X, and tried to get X started.  I get this error I can't really understand.  I'm going to type it below so maybe someone can point me in the right direction?  Thanks in advance everyone.

xauth:   creating new authority file  /home/ralph/.Xauthority
xauth:  (argv):1:  bad display name ":0" in "remove" command
xauth:  (argv):1:  bad display name ":0" in "remove" command
 
  and then X exits - what does this mean??
