Try passing some arguments to the kernel command line within you pxelinux.cfg 
dir.  On my debian client, I pass the following.  

ip=dhcp root=/dev/nfs

The full option for my  lubuntu boot from iso image looks like this

        MENU LABEL LUBUNTU 10.04 Beta
        kernel lubuntu/vmlinuz
        append initrd=lubuntu/initrd.lz ip=dhcp boot=casper netboot=nfs 
nfsroot=192.168.4.1:/mnt/nfs/lubuntu nosplash


Hope this helps,
