Syslinux - Dec 2010 - problem booting (Fedora) LiveCD ISO over PXELINUX

This is an issue I've researched quite a bit on bug lists, and looked
in the Syslinux Wiki for a way to do this, but haven't yet found a
solution.

1) I have an existing Fedora 13 LiveCD which I burned to a CD and
tested on  a system without issue.

2) I then took that same ISO and dropped it in my pxelinux.cfg/default
for being able to boot over the network. I made sure to extract the
proper vmlinuz and initrd from the LiveCD and make it available to my
PXELINUX Config:

label LiveCD
 MENU LABEL LiveCD
 kernel livecd/vmlinuz0
 append initrd=livecd/initrd0.img media=network
root=live:CDLABEL=F13-LiveCD-POC-20101201-122711 rootfstype=auto ro
liveimg rhgb rd_NO_LUKS rd_NO_MD rd_NO_DM ramdisk_size=164212
init=/bin/init  iso1=nfs://imagesrv/fedora-livecd.iso
iso1mnt=/mnt/bootdevice


What I got was the following error message:

Boot has failed, sleeping forever.

Am I specifying the wrong filesystem or bootdevice?
Has anyone been able to get this to work with a LiveCD? Seems like the
Fedora Forums Bugzilla most people are giving up on this. My theory is
if it works from a CD, it should work over PXELINUX. All help is
appreciated.

I should clarify the error message:

No root device found

Boot has failed, sleeping forever.

This is not a Syslinux/PXELINUX question but a Fedora/Anaconda question.
 Things are well past the Syslinux stage at this point.

Is there general documentation on the flags required to boot an ISO
using pxelinux?

There is no such thing.
