No hardware hipersockets doesn't necessarily mean that you can't use the guest LAN. Are you using the evaluation version of SuSE 7.2 or are you using the old SuSE with the 2.2.16 kernel? If the former you can define a guest LAN and set up SuSE to use it. If the latter, then you are definitely stuck using point to point.
