Broadcom & NVIDIA PXE Roms are the worst in my experience - slow and buggy.
I've had to upgrade ROMs on motherboards with these before.

I'd start by making sure you're using the latest tftpd-hpa server. Then test booting 
the latest pxelinux.0 from syslinux.zytor.com.
If that works, then your grub2 build process might need a look-see.

grub-mkimage --output=core.img --prefix="(pxe)/defaulttftprootdir/grub2" 
$MODULES
