I have the same problem with a Thinkpad X301, the Suspend2Ram/Suspend2Disk buttons ceased to work with some update in the last two weeks.
Yesterday I made a aptitude full-upgrade to sid and KDE 4.2x the problem persists .. Is there a site somehere which explains what components are needed / how they work together to provide this functionality ? WR, Bruno
