+With my ATI X1400 graphic card an a IBM/Lenovo T60 with the proprietary driver, suspend and hibernation doesn't work out-of-the-box. Fortunately the fix is simple: just make changes to the acpi-support file in /etc/default((only tested on a alpha/beta install)).
+Make it look like this and your good to go.
