Edit /var/lib/tftpboot/ltsp/i386/lts.conf and change SCREEN_07 to 
"xdmcp".  This changes what the client does during boot.

The above method will not allow this either if primary GDM server is the 
same as the dead server.  How does this work for pre-LDM LTSP?

This is actually an LDM bug.

I was planning on using this as an advantage by having a LDM-specific 
login theme for K12Linux.

This should be configurable with /etc/sysconfig/desktop but it does seem 
to be broken at the moment.  (Strangely, I can't even get it to work 
with GDM either.  The option itself might have broke.)
