[opensuse] how to install "suspend to disk"

Hi there, this is my first post to this forum. Please tell me if there is a more appropriate one to ask question as the following if you think one exists. After changing both main board and upgrading from SuSE 10.1 to 10.2 I can not suspend to disk any more. The respective entry is missing in the shut down menu. Is there a way to "install" it? thanks, robert
