gPXE from freedos is a great idea.
http://syslinux.zytor.com/wiki/index.php/Sanboot.c32 says it requires
gPXELinux.0 so...looks like it would be the only option as to booting from
CD.

Have you tried just chainloading gPXE using the bin/undionly.kpxe image to
san boot?  sanboot.c32 is, for the most part, untested.  "It should work" as
the saying goes.  but you never know...
