Don't know about Norton, but here are some things you could try.
UDPCAST - http://udpcast.linux.lu/
That can boot from a single floppy, and uses multi-cast to make images. Not 
sure if it has a PXE option, or could be easily changed since I haven't setup 
a PXE system.

G4L or G4U, are ghosting type programs that use dd, gzip or lzop or bzip2, 
and ftp to make and restore images. G4U can boot from floppies, G4L 
requires CD, but atleast one user was able to create a PXE from the image, 
but again, I have not done it myselft. 

I used Norton Ghost before, and we had a site license for the 2000 version 
at my college, but then it failed on the new Linux partitions that came with 
FC3, so I found a program that would work, and G4U and later G4L did.

UDPCAST works great for doing imaging of many machines, but it does 
flood the network, so I usually disconnect the lab from the rest of the 
network when doing an image.
