Mainline gPXE does not have NFS support but I have patches here:

I am not 100% happy with the code and haven't had time.  However, the
code is functional for NFSv3 TCP booting.

You don't need to use wraplinux.  gPXE has support for the bzImage
format that Linux kernels use.

Try booting a script like this one:
#!gpxe
kernel tftp://145.239.198.49//jetlinks/ss/tftpboot/vmlinuz-2.6.18-1.2798.fc6
ro root=/dev/VolGroup00/LogVol00 console=tty0 console=ttyS0,9600
initrd tftp://145.239.198.49//jetlinks/ss/tftpboot/initrd-2.6.18-1.2798.fc6.img
boot
