PXE-booting rescue mode

Hi,
In previous versions of Fedora (i.e. Fedora-9), it was possible to do a PXE-boot
of a rescue image, by supplying a ks.cfg that looked something like:
lang en_US
keyboard sv-latin1
firewall --disabled
selinux --disabled
text
network --bootproto dhcp
nfs --server=<hostaddr> --dir=<dist>/Fedora-9
which was very handy for partitioning disks, etc, with Fedora-10 this stopped
working due to the following code at the end of rescue.py
if anaconda.isKickstart:
from kickstart import runPostScripts
runPostScripts(anaconda)
else:
runShell(screen, msgStr)
and with Fedora-11 there is even more weirdness:
if anaconda.isKickstart:
log.info("No Linux partitions found")
screen.finish()
print(_("You don't have any Linux partitions. Rebooting.\n"))
sys.exit(0)
Is there any supported way to PXE-boot a rescue image for Fedora-11? At the
moment I have put a slightly modified rescue.py in RHupdates (I know, it's a
terrible hack...):
