1) I've actually had pretty decent luck with the VMware PXE stack on
some platforms, including pushing 17+MB/s with another version of
lpxelinux.0 and fetching 90+MiB initrd files.
2) I've generally has better luck loading pxelinux.0 first then gpxelinux.0.
3) Why not use the CONFIG directive/config.c32? modules that need to
be at different versions?
