Tried kernel 2.6.15-21-386,2.6.15-22-386, and 2.6.15-22-686. No difference, system tries to resume but xserver is not resuming. Sometimes resume is working, sometimes not. Rigth now I try it with ACPI S1 sleep. This seems to be more reliable. -- Suspend hibernate on T41p not working https://launchpad.net/bugs/43833
