Thoughts:
1.  The client should be sending an ARP request for the tftp 
server.  If this is not happening, then something is wrong with 
next-server in your version of dhcpd.

2.  Try running tcpdump on the tftp server.
tcpdump -i eth0 host {ip that client should have gotten}

3.  Can you manually run tftp to the server?

4.  tftp is normally set to log to /var/log/daemon.log.  Try 
increasing the verbosity and see if anything shows up.

5..  You have the filename as /ltsp/i386/pxelinux.0 But you have 
root-path = /opt/ltsp/i386/ Do you actually have two separate paths?

Remember that tftp usually runs in chrooted enviroment, so the 
path to pxelinux.0 is relative to the jail that tftp runs in.  e.g.

If I allow tftp to have access to /opt/tftp/
and then I have /opt/tftp/lstp/pxelinux.0 as my boot file
then the path I give for the filename is /lstp/pxelinux.0

If your paths are correct, then it means that you have permitted 
/opt via tftp, which I would regard as a security risk. (Not a 
huge one, but still...)
