Latest Hoary liveCD and screen resolution

[Eamonn Sullivan]

Further on this: The Hoary Array 4 live CD correctly identifies the
graphics chip set, the monitor and all of the supported resolutions,
but once Gnome starts I just get two choices in
Desktop/Administration/Screen Resolution

800x600 (bad)
640x480 (worse)

I guess I don't understand how Xorg configs work. Can I use
dpkg-reconfigure while running the live CD? What package do I
reconfigure?
