You could always use the IPAPPEND=1 option to the pxelinux.cfg/foo
file.  This gets the PXE bootstrap to forward the information the PXE
DHCP request got on to the kernel.

It's not quite as tidy as keeping it all in the DHCP server, as you
don't get to pass in options like NFSROOT, etc.  But these can all be
specified in the PXE boot config, I find that it's easier to work
with.

here's my pxelinux.cfg/C0A80105 as an example:

PROMPT 0
default fai-install
label fai-install
kernel k8
append root=/dev/nfs FAI_ACTION=install 
FAI_FLAGS=verbose,sshd,createvt,syslogd 
nfsroot=192.168.1.42:/usr/lib/fai/nfsroot console=ttyS0,115200
IPAPPEND 1

You also need to use this, if your NFS root server isn't the same as
your DHCP server, due to a deficiency in at least the 2.2.20 kernel
that ships with woody's FAI.
