Ah, I (think I) forgot to tell you that I had to put 'ip=all' in the 
pxelinux.cfg, otherwise you either hang or get kernel panics.

Well, what's stopping you from adding it?  :)

Sure, I'll post it for all to see, hopefully the list formatting won't 
butcher the config - I use a 30" monitor, so I don't restrict my config 
files to 80 chars in width.  That being said, the only function I hacked 
in there was configure_networking, so here it is:

configure_networking()
{
    # RYANS 2008-12-05 - add debugging output
    echo -e "\n\nInside configure_networking\n\n" > /dev/console 2>&1
    # networking already configured thus bail out
    [ -n "${DEVICE}" ] && [ -e /tmp/net-"${DEVICE}".conf ] && return 0

    # RYANS 2008-12-05 - set timeout to 30
    # support ip options see linux sources Documentation/nfsroot.txt
    case ${IPOPTS} in
    none|off)
        # Do nothing
        ;;
    ""|on|any)
        # Bring up device
        ipconfig -t 30 ${DEVICE}
        ;;
    dhcp|bootp|rarp|both)
        ipconfig -t 30 -c ${IPOPTS} -d ${DEVICE}
        ;;
    *)
        ipconfig -t 30 -d $IPOPTS

        # grab device entry from ip option
        NEW_DEVICE=${IPOPTS#*:*:*:*:*:*}
        if [ "${NEW_DEVICE}" != "${IPOPTS}" ]; then
            NEW_DEVICE=${NEW_DEVICE%:*}
        else
            # wrong parse, possibly only a partial string
            NEW_DEVICE=
        fi
        if [ -n "${NEW_DEVICE}" ]; then
            DEVICE="${NEW_DEVICE}"
        fi
        ;;
    esac

    # RYANS 2008-12-05 - just source net-*.conf and be done with it
    # source ipconfig output
    #if [ -n "${DEVICE}" ]; then
    #    # source specific bootdevice
    #    . /tmp/net-${DEVICE}.conf
    #else
        # source any interface as not exaclty specified
        . /tmp/net-*.conf
    #fi
}
