How fancy is your pxe config file?  Could you just burn the contents of
your /ftfpboot directory to a CD-ROM and use isolinux to load the files
from the CD-ROM?  Eliminate DHCP, TFTP, and PXE entirely.

If you get the kernel and initrd loaded with the right commandline, the
kernel will initialize the network interface and let you finish the process
via TCP/IP...
