Syslinux - Apr 2003 - PXELINUX on top of Etherboot?

Question for people...

Has anyone actually tried running PXELINUX on top of Etherboot?  There 
is something in Etherboot 5.1.7 called FREEBSD_PXEEMU, which seems to be 
a PXE stack subset, in particular it seems to support the following calls:

PXENV_GET_CACHED_INFO
PXENV_UDP_OPEN
PXENV_UDP_WRITE
PXENV_UDP_READ
PXENV_UDP_CLOSE
PXENV_UNLOAD_STACK
PXENV_UNDI_SHUTDOWN

This happens to be pretty close to the subset used by PXELINUX, with two 
exceptions: PXELINUX will also invoke PXENV_STOP_UNDI (for version >= 
2.00) or PXENV_UNDI_CLEANUP (for version < 2.00).  I'd be really curious 
to see how this would play out.

There are of course also other kinds of concerns, e.g. if the detection 
mechanism works properly, and if it stomps on memory it shouldn't be.

I'm sorry if this has happened to be public knowledge to everyone but 
myself for a long time.  If this happens to work, though, I'd like to 
post it on the PXELINUX web pages, and if not, I'd like to see what I 
can do to help debug it.

I did not even succeed in compiling etherboot on Linux when FREEBSD_PXEEMU
is activated. In Addition the comment in the configfile tells, that
FREEBSD_PXEEMU only works with DOWNLOAD_PROTO_NFS enabled.
