yes, your USB/CD can still get an IP of the DHCP server, but you 
can "hardcode" you NFS-Server to your cd.
simply add this this to your kernel boot prompt (in grub)

  ip=dhcp root=/dev/nfs nfsroot=192.168.1.1:/srv/fai/nfsroot-2.6.39 boot=live  FAI_FLAGS=verbose,sshd,createvt FAI_ACTION=install

So you are not longer dependent on any PXE/TFTP setting on the DHCP 
server
