Customer is doing a kickstart install on an IBM p630 7028-6C4 with no
video cards.  They are generating a ks.cfg using
redhat-config-kickstart.  The kickstart file appears valid and was
confirmed to be internally.  However, in anaconda we are detecting
that the machine has no video cards, assuming it is a headless
install, but later (in kickstart.py) looking for id.xsetup.skipx but
id.xsetup is None.

The piece of code in anaconda that detects the headless machine is:

if not isHeadless:
    #
    # Probe what is available for X and setup a hardware state
    #
    # try to probe interesting hw
    import rhpl.xserver as xserver
    skipddcprobe = (skipddc or (x_already_set and flags.test))
    skipmouseprobe = not (not os.environ.has_key('DISPLAY') or
flags.setupFilesystems)
                                                                     
                            
    (videohw, monitorhw, mousehw) =
xserver.probeHW(skipDDCProbe=skipddcprobe,
                                                    skipMouseProbe =
skipmouseprobe)
    # if the len(videocards) is zero, then let's assume we're isHeadless
    if len(videohw.videocards) == 0:
        print _("No video hardware found, assuming headless")
        videohw = None
        monitorhw = None
        mousehw = None
        isHeadless = 1
    else:
        # setup a X hw state for use later with configuration.
        try:
            xcfg = xhwstate.XF86HardwareState(defcard=videohw,
                                              defmon=monitorhw)
        except Exception, e:
            print _("Unable to instantiate a X hardware state object.")
            xcfg = None

Current workarounds suggested are to not use the "skipx" kickstart
directive for a headless machine.
