Monitor on DisplayPort doesn't wake up

When a box with a Radeon HD 8490 (PCI ID 1002:6771, Subsystem 103c:90b8) connected to a Samsung SyncMaster SA850T enters powersaving mode, the monitor doesn't come back on after waking it up.
ssh-ing in from another box and running "xrandr -s 1280x800 ; xrandr -s 2560x1440" brings it back to life. ("xset dpms force on" doesn't help).
