If you use the LTSP-PNP setup, your client and server installation 
architectures have to match.  So if your clients need i386, then you 
have to install Ubuntu i386 on the server as well.

If you really want x64 on the server, then you have to use the classic 
LTSP setup with a chroot environment and i386 installed there in order 
to generate an i386 client image.
