Suspend/ Resume on Suse 9.3 x86_64 on Acer Ferrari 4005 not working

I am new to Suse 9.3 x86_64 and I like it very much. I would love to have suspend resume work on my laptop. I was delighted to see that Suse 9.3 x86_64 seems to have support for it in KPowerSave "Suspend to Disk" menu. However, when I run it, the screen writes some text but never goes blank and system never shuts down entirely. I then do a hard reset by holding down the power key. When I reboot it appears to just start as if it were never suspended. What am I missing? Thanks. -- Regards, Farrukh
