Did you ever get s2ram to work on this box ? (when not using DVI?)
What happens with driver 1.4.8 from unstable?

Ok there's a bug in the way the driver retrieves the VideoRAM after suspend.
The crash comes from the pixman lib and is similar to upstream bug

startup? Loading a real window manager with shiny effects? Or just
loading a simple xdm?
