Well, the latest initramfs-tools package from intrepid didn't quite do 
the trick, but led me to a solution.  I ended up making the following 
changes to /scripts/live:



638:    # make /scripts/live use configure_networking just like 
/scripts/nfs does
639:    #ipconfig ${DEVICE} | tee /netboot.config
640:    configure_networking



And this change to /scripts/functions, at the bottom of the 
configure_networking function:



356:     # If we don't know the device ahead of time, we need to check 
net-*.conf
357:     # source ipconfig output
358:     #if [ -n "${DEVICE}" ]; then
359:     #       # source specific bootdevice
360:     #       . /tmp/net-${DEVICE}.conf
361:     #else
362:        # source any interface as not exactly specified
363:        . /tmp/net-*.conf
364:     #fi



Basically, when we PXE boot with the pxelinux.cfg file set up by 
fai-chboot using ip=dhcp, we end up using the /scripts/live shell 
script, which uses the 'ipconfig' binary.  But, we need to tell ipconfig 
to time out for an interface for which it can't find a DHCP server, 
which is what configure_networking does using 'ipconfig -t'.  I'm not 
sure why /scripts/live doesn't use the configure_networking script by 
default, or if this is even the right thing to do, but it works for me, 
no matter which interface I have cables in or which interfaces can 
contact a DHCP server via ipconfig.  If anybody has any comments, please 
feel free to voice them.


HTH,
