kernel is loaded by tftp - so nfs isn't the problem. Find a tftp client 
and see if the kernel is available to it. I suspect the kernel isn't 
world-readable and executable. It may also be that tftpd isn't available 
beyond localhost - did you edit hosts.allow?

See http://www.nber.org/sys-admin/FreeBSD-diskless.html for our 
experiences with diskless boot.
