Vista and OpenSUSE; Hibernate, Sleep/Suspend Error

[GnuBoi]

Previously, in my dell laptop with vista the sleep and hibernate used to work fine and great. And i have now created a dual boot system of OpenSUSE 11.1 and Vista. And now the Sleep and Hibernate feature of vista does't work neither works the hibernate and suspend of OpenSUSE. Can anybody tell me what to do to make them work?

Thanks in Advance....
