Would the InitRD+CmdLine feature be useful to you?  
http://etherboot.org/share/sha0/gpxe/src/bin/gpxe.lkrn

This gPXE build is a "Linux kernel"-format binary which you can load 
with any bootloader capable of loading Linux kernels (bzImage).  You can 
pass a gPXE script as an initrd and this gPXE will find it.

For GRUB, that might look like:

title Load gPXE
  kernel /gpxe.lkrn
  initrd my_script.gpxe

I don't know if that's useful to you or not.  Can be handy with QEmu 
without constantly rebuilding gPXE.

# qemu -kernel gpxe.lkrn -initrd my_script -hda /dev/null
