| How do you specify nfs swap in the fstab file? I have been trying the

You don't, it is done via the bootp or dhcp record option 128 for example
          option option-128 "192.168.2.254:/usr/work/netboot";
You then have to make the swap file in that directory of format
	swap.<IP of client>
Use dd to create the file by copying /dev/zero for the size you want.

Note during boot up the kernel will tell you what it is using for 
swap via this request.
